FIRST LOOK AT IPAD 2: What's new, unchanged and still missing First look at Apple iPad 2: what's new, unchanged and still missing

IFixit warns that those who dare to peer into the insides of the iPad 2 on their own risk cracking the glass front panel, which is thinner than that from the original iPad (0.62 mm vs. 0.85 mm) and glued on rather than attached via tabs. A heat gun was needed by iFixit to disassemble the device.

Once inside, iFixit took a look at the iPad 2 battery, which Apple says offers 10 hours of life before recharging, just like the original (boasting 3 big Li-Ion cells). Here's what iFixit found: "A 3.8V, 25 Watt-hour unit. That's just a hair more than the original iPad's 24.8 Watt-hours, so any improved battery performance can be attributed to software and other hardware improvements."
