The new iPad may seem — in Apple’s own words — resolutionary, but nothing is absolutely perfect. Now that the tablet has been out in the wild for a few days, early adopters have been able to bank a few issues that anyone still contemplating a purchase should consider.

Overheating?: This is a topic that’s getting a lot of chatter on Apple’s support forums. It seems that the new iPad is running hotter than its predecessor, and several people on the forums have noted that they get an error message saying the iPad needs to “cool down” when they’ve been using their tablets for long periods of time. Many users identified the same “warm corner,” left of the home button.

What isn’t clear is how serious the problem is. Some users raising concerns about the higher temperatures say they noticed them while the iPad was on a bed or in direct sunlight — scenarios that will fluster almost any gadget.

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 a better battery and better graphics processor, but is worth noting if weight is an issue for you.

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.

No Siri: Many people were expecting Siri on the iPad, so 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.

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.

International users: International users have been complaining that they can’t use their iPads on “4G” networks. The Australian reported that some carriers in Australia, for example, have done away with advertising the 4G features of the iPad altogether, since the airwaves approved for 4G in the U.S. and other countries aren’t the same.
