What We New - What We No Now!One of the reasons that Windows took off in the first place was working more easily with devices - in those days, printers. Support for a wide range of devices is one of the reasons it's hard to other OSes to challenge Windows but Microsoft would like to get hardware manufacturers to do more with the sensor platform and DeviceStage interface it introduced in Windows 7.
With Windows 8, Microsoft wants to see "PCs use location and sensors to enhance a rich array of premium experiences. Users are not burdened with cumbersome tasks that Windows can accomplish on its own. Users are neither annoyed or disturbed by the actions the PC takes. Instead, the PC's behaviour becomes integrated into users' routine workflows. Devices connect faster and work better on Windows 8 than on any other operating system."
The 'current thinking' is for Windows 8 to include Microsoft's own Wi-Fi location service Orion (which has 50-100m accuracy in North America and Western Europe but falls back to using the location associated with IP addresses elsewhere, which can be as bad as 25km).
Orion will be used in Windows Phone 7 (as well as Hawaii, a Microsoft Research project to build cloud-enabled mobile apps which refers to Orion as a 'prototype service'). Microsoft partnered with Navizon in March to use their Wi-Fi and mobile network location database but the slides claim that Orion is buying a bigger database than Navizon's 15 million access points, giving it 40 million compared to Google's 48 million (neither matches the 120 million Skyhook gives the iPhone).
Location will be available to the browser as well as to any app that's written to use it (music players as well as mapping tools), and web apps will get access to webcams.
Microsoft is emphasising the privacy aspect of location and webcam use, with mockups of how apps can ask for location and users can choose to deny it or only allow it once. And it's also asking PC manufacturers how many devices they plan to put GPS in and offering a Device Stage interface for using a PND like a Garmin nuvi as a GPS source for your PC.
LOCATION PRIVACY: Web apps can see your location and use your webcam – but you get to control that to protect your privacy
As we've said before, Device Stage will become the standard way you work with devices; Microsoft previewed the options you'll get with a featurephone and a webcam as well as GPS.
Along with GPS, Microsoft is expecting PCs to include infrared sensors as well as the ambient light sensors that are becoming common, and the accelerometers that are in tablets with rotating screens.
Put that together and the PC could know which way up it is, whether there's anyone in front of it - or near it and what the lighting is like in the room. So when you walk into the room your PC notices and wakes itself up so by the time you sit down the webcam is ready to recognise you - and no waiting or having to line your face up with a box on screen.
If this works, the camera will pick your face out of the room, like Photo Gallery finding a face in a picture (hopefully without thinking the face in a picture on the wall is you). When you walk away it goes back to sleep again.
We like the idea of rotation lock buttons on 'Lap PCs' so you can move them around to control a game without flipping he screen repeatedly; again, if you look away from the game, Microsoft envisages it pausing automatically and if you pass a slate to someone it will switch to their account automatically.
What's in: USB 3, Bluetooth hands free and headset profiles (mono and stereo audio).
What's out: Microsoft has no plans to support Bluetooth 3.0 + High Speed, 1394 might be deprecated and Microsoft seems to expect USB 2 ports to be phased out in favour of USB 3 within the lifetime of Windows 8.
What's under consideration: Bluetooth Low Energy (from Bluetooth 4.0). What's not mentioned: Intel LightPeak, although Microsoft does ask if it's missing anything on its list of connectivity.
Windows 8 will know who you areWith better ways to log in to your PC, like your face, Microsoft is considering giving Windows 8 a way to "securely store usernames and passwords, simplifying the online experience".
Your Windows account might connect more directly to the cloud than just having a Windows Live ID, logging into web sites on your behalf; there's very little detail on this but it could revive the CardSpace technology introduced in Vista but not widely adopted.
FACE LOGIN: Forget passwords; Windows 8 will use the webcam to find and recognise your face (probably)
Put it all together and you get some welcome improvements. It's impossible to say if Microsoft can come up with a simple enough programming system to appeal to the developers it wants to create Windows apps to rival Apple's App Store.
Until we see some code in action it's also hard to say if the 'instant on' and better battery life will transform the PC experience to compete with lightweight systems based on Android (or if Microsoft can deliver them) and make the PC scale from the tablet to the heavyweight systems we have today – which Windows has to do if it's going to stay the dominant PC OS.
Everything else here is incremental – as it would have to be if Microsoft really expects to release Windows 8 in 2011, but it's potentially disappointing if it comes in 2012 and there's nothing else exciting in Windows 8.
Windows 8 gamingMicrosoft hopes to use Windows 8 to relaunch itself at the forefront of PC gaming, with Redmond ready to put its weight behind the platform once more.
"Windows 8 will represent a real new push into PC gaming," a source told TechRadar. "Gaming will be a key component for the whole OS."
A Windows app storeMore than 30 app stores have launched in the last year and Microsoft isn't the only company copying Apple here; Intel has its own app store for Atom PCs. PC makers like the idea - apparently at the first forum they commented that it "can't happen soon enough".
With an app store, Microsoft hopes to attract more of the type of developers who are currently building smartphone apps and it wants them to create apps that make Windows the best place to use web apps (a job advert last October claimed "we will blend the best of the web and the rich client by creating a new model for modern web applications to rock on Windows".)
According to the slides, "Currently the indication is that app development will move to the Web. There is significant opportunity for Microsoft if hardware capabilities, and OS services and Web could be integrated into a hobbyist developer toolset."
The 'tailored experiences' Microsoft talks about for Windows 8 sound like smartphone apps; the checklist includes fast installation and updates for engaging, social, extensible, ad-supported or 'freemium' apps.
If smartphone-style apps sound too simple to be worthwhile on Windows, Microsoft wants apps to be extensible so you can share information between them - perhaps using a mix of simple apps together. It sounds like the 'mashups' that we were all going to be making online until it turned out you'd have to learn to program.
The Windows Store will be branded and optimised for each PC manufacturer. Your settings will follow you from PC to PC, as will your apps (although some slides refer to this as a possibility rather than a definite plan) - but you'd need an HP ID to log into the 'HP Store powered by Windows' and get your HP-specific apps. Microsoft doesn't plan to make money from the store; the slides call it "revenue neutral".
Windows 8 tabletsThe leaked slides are aimed at PC manufacturers who are interested in new form factors - and in getting a share of the iPad market - so it's no surprise one of the key PC form factors is a 9" slate (which Microsoft, having obviously got the point of all those iPad ads, is calling a Lap PC), optimised for web and media, casual gaming, reading and sorting email, IM and social networking.
LAP PC: Using the Lap PC to read a magazine and play a driving game
Microsoft promises big improvements to the on-screen keyboard: it will be "easily launched, text prediction is more accurate, the UI is more usable, and throughput is increased for everyone".
There's also the workhorse PC (which is also referred to as a laptop, because Microsoft is only talking about consumers and not business users) and the family hub (an all-in-one touchscreen system that can go in the kitchen or the living room as a media centre) which is for casual gaming, web and media as well as more demanding apps like organising and manipulating media.
Key to making a successful Windows tablet is apps with user interfaces that change depending on the form factor (touch and gestures instead of keyboard and mouse), but Microsoft is also looking at stereoscopic 3D and high colour displays and natural input that uses touch, voice, 3D gestures ("on the horizon"), and facial recognition.
3D SUPPORT: Windows 8 will play 3D movies and games, but don't ask Microsoft to pick its favourite format yet
Optimising "for smaller screens" will help netbook users as well; Windows 7 gets key dialog boxes to fit on a small screen but not all apps do.
Note: I am aware of the run on words at the top center of this posting.
