Kind of amusing that you're bashing a $500 device when your $320 netbook has been in for repair FOUR TIMES. People always rail on the interchangable battery thing, but I've never carried spare batteries for ANYTHING I've owned. If you're on the move, do you really want to lug around a couple extra pounds? They list 10 hours of battery life including video playback, which, judging by my experiences with a 1st gen iPod touch, is believable.
This thing is more a web-surfing super eBook reader than a true netbook, but in my opinion, it looks awesome. No, it's not a hacker's dream come true mega-portable computer, it's a "normal" person's digital media device. It's for eBooks, music, photos, the web and email and it's designed to do those tasks in a sleek, sexy, simple manner.
This happens with every Apple product announcement. People speculate and expect it to have every feature under the sun, cost next to nothing and be 100% open source, cure cancer, make coffee and have its only environmental by-product be rainbows. Sorry, people, this is the real world. This product looks awesome for what it's designed to be. It's not going to replace your netbook for hacking perl on your favorite geek project and it's not supposed to.
