In the week since customers have gotten their hands on the new iPad, complaints have piled up. Owners have said Apple’s newest tablet overheats, has WiFi connectivity issues and takes a long time to recharge, to name just a few of the problems.
More fragile than iPad 2

Warranty provider SquareTrade conducted a drop test on the iPad 2 and the new iPad and found that the newer tablet suffered more damage when dropped from waist and shoulder heights. SquareTrade said the new iPad's screen shattered and "almost popped off," while the iPad 2's screen just shattered.
Takes too long to recharge

PCWorld has tested 43 tablets and found that the new iPad needed the most time to completely juice up its battery. How long did it take? Almost six hours, the magazine says.
"WiFi-gate"

Since the launch of the new iPad, some customers have been complaining about WiFi connectivity on Apple's new tablet, Gizmodo reports.
Runs hot

After buying the new iPad, some customers noticed that Apple's latest tablet had a heat issue. On March 20, Consumer Reports released results of its heat tests that it conducted on the new iPad. The magazine found that the heat of the new iPad tablet reaches temperatures of around 116 degrees -- about 13 degrees warmer than the iPad 2.
Heavier

The new iPad is a couple of ounces heavier than its predecessor, the iPad 2, which won’t make a difference to most folks. But if you carry your iPad a lot, or like to hold it with one hand, you may notice the extra weight. It’s a small tradeoff for better battery life and a better graphics processor, but is worth noting if weight is an issue for you. The battery lasts a long time after you charge it, especially for a 4G device.
No Siri

Many people were expecting Siri on the iPad. But while the voice dictation feature that has been added to the tablet is quite good, users are lamenting that they can’t tell their iPad to schedule appointments, conduct Web searches and note reminders for them.
Sucks life out of data plans

There have been reports that the new iPad quickly eats up data plans. USA Today's personal tech writer Edward Baig said that "less than 24 hours after purchasing" a 2GB plan for his new iPad, he received a message saying that he didn't have any data left in the plan.
Storage

The HD display on the new tablet is great, but has also required a boost in the sizes of some apps. Just note before buying that you may not be able to carry quite as many apps as you have in the past.
No LTE Facetime

The inability to use Facetime over cellular networks has vexed Apple users in the past, and seems to be even more of an annoyance on the 4G iPad, since the network is so fast.
