Thats just his world renowned, type A personality coming out. No one has ever said Jobs is a nice person.

According to the specs page, it's with Wi-Fi
Up to 10 hours of surfing the web on Wi-Fi, watching video, or listening to music
Of course, it also says 10 hours for music

Who makes the display?
Wired seems to think it is LG. If so then it is possibly using Enhanced IPS.
According to Wikipedia:
Also from Wikipedia:
The Korea Times has an article detailing LG IPS technology:
So basically, this guy isn't considering all the facts. Apple isn't going to tout 10 hours if it gets less than 3 like he claims![]()
I'm slowly warming to the iPad. I think I'm going to have to actually use it first--that's usually what sways me one way or another with Apple products when I'm on the fence.
Mossberg was saying no e-ink means worse battery life and isn't that a problem, but I think Steve had a good point: it's 10 hours but who is going to read for 10 hours straight?
Answer:And who is going to read that long... with no way to reach a power outlet?
Answer:
Backpackers, campers, mountain climbers.
Then again, one of them was Australia.

Sorry if this is a dumb question, but:
Is listening to music while reading a textbook considered multi-tasking?
well the 140 hour music playback is nice too; and if 10 hours doing video is accurate, even a NY to London flight is covered.

The vast vast majority of people that would be interested in a device like this will be in the vicinity of a socket at some point or another during the day...
I think 10hours is doable. 140hours of music playback probably possible as well. (remember, that's with screen off the whole time, volume set to 50%, and Wifi turned off). In a test with an iPhone 3G, I got a bit over 24hours of music playback with those conditions, and in airplane mode (same as turning off WiFi on iPad).
Comparison with MBA:
- MBA has 50% larger battery than iPad (40W vs. 25W)
- Air runs a 1.8GHZ processor, 9400M graphics, and a 13-inch display, full OS X with lots of system and background processes.
- iPad runs slower (and more efficient - Intel even admitted ARM chips are more efficient when iPhone came out) processor, much less hungry graphics, 3.5-inches smaller display, iPhone OS optimized for ultra-mobile, and only a few system processes and a single user processes at once.
- I've gotten slightly over 5hours with a MBA, I think 10hours is possible with an iPad. However, that will be with low screen brightness.
The display is the power hungry part of iPad.
Going on the assumption that the machine must be able to run on it's power adapter and still have a little something left over to charge the battery, how about this comparison:
Battery Watt-Hours vs. Power Adapter Watts vs. rated hours.
MacBook 60, 60, 7
MacBookPro 73, 60 or 85, 7
MBA 40, 45, 5
iPad 25, 10, 10
Either the power adapter on the iPad is inadequate compared to the other designs, or the rated hours make rough sense. i.e. with the device going full blast, the iPad's battery will last roughly twice as long as the notebook's.
I posted this info in the general ipad discussion forum yesterday. I am kind of pissed that this is first page news today. Thanx for the credit.
One thing I have been wondering about is whether or not it will be able to stream music to an Airport Express with AirTunes with its implementation of iTunes or if that will require a separate computer with iTunes.
Just something I have been wondering about. Would only make sense if the iPad could stream for itself.
