My new ipad is quite warm on the left hand side, even through a case - sounds like it's fairly common. I'm wondering if this is normal, or if I should take mine back for an exchange.
OP what model is your's?
On my 64GB Wifi only, I haven't noticed any heat.
It's a 32gb Verizon version. It's a good point - some memory chips could run hotter.
I understand the battery and performance requirements have increased, it's just not Apple-like for their products to get warm during light usage such as browsing web. iPhone doesn't get hot unless you're playing graphics-intensive games. At least I'm not alone with this.
If it's like the iPad 2, the memory is on the right with most of the circuitry on the left.
I asked about the model, since I wondered if it could be the cellular circuitry. If it got hot while browsing through the cellular antenna, this could be it.
