The iPad 2 is great and all, but there are things I miss about the iPad 1. 1. Build quality. The iPad 2 is solid and slim, but from a strictly build quality standpoint iPad 1 wins. This is due in part to the added thickness of the case which of course I do not miss. Little touches like the tiny screens over the speaker, the beveled edge of the aluminum, all gave the iPad 1 a slightly more lux look and feel. The iPad 1 had more genetics from a Macbook unibody; the iPad 2 is closer to an iPod Touch. If the iPad 1 was a Leica M6, the iPad 2 is an M9. Finish wise the iPad 1 wins too. The iPad 2 is basically a glued sandwich. The iPad 1 was an elegant exercise in precision engineering and pressure fitting. My iPad 2 and others' have exhibited rough edges and uneven screen fitting. And of course backlight issues are accentuated in this thinner design. 2. Heat. iPad 1 kept its cool. iPad 2 heats up noticeably. 3. Battery. iPad 1 sipped power. iPad 2 definitely drinks. Guzzles, no, drinks, yes. 4. Speaker. The grill looks and feels cheap (see#1). And while it may be better spec'd sonically, it's quieter and less punchy than iPad 1. This is likely due to the rear facing position of course; another byproduct of slimness. 5. Ergonomics. The iPad 2 feels great in the hand, but there have been moments where I wish the edges weren't quite so thin. Holding for extended periods in the same posititon can yield a nice crease in the hand from the corner digging in. The flat sides of the iPad 1 served an ergonomic purpose despite their thickness. Would I trade back? No, but the added benefits of size and speed of the iPad 2 do come with a few trade offs.
