Wally asks why get an iPad in addition to his iPod Touch and Kindle.
Maybe with both those tools he has no need ... but for many the iPad might replace both those tools for about the same total cost. For me an iPad would eliminate the need for a Kindle, and maybe a laptop (a non-mobile computer + iPad could be enough for how I work), but I would keep my iTouch.
But in case you missed it Wally (and anyone else who sees little advantage over an iTouch or a smart phone):
1) the iPad will be far better for a lot visual media viewing than an iTouch: web browsing; photo and video viewing and basic photo manipulation; reading books, magazines and newspapers in electronic versions, etc. I suspect that magazines and newspapers like the New York Times wish to transition from free web-sites to primarily offering electronic subscriptions via Kindle, iPad and such devices: the magazine and newspaper desperately needs a new revenue source!
2) compared to book readers like Kindle, one obvious advantage is color and a far fuller web browser experience. Another is some limited content creation ability: email, iWork for word processing, spreadsheets and presentations, and whatever other iPad Apps come along. But Amazon has opened up software development opportunities for Kindle, so maybe this is where future Kindle models are headed too.
3) compared to laptops and flip-screen tablets, it is far more hand-holdable for reading books, websites and such, and "away from a desk" usage.
One obvious criticism is that the iPad is no substitute for a laptop (even the shrunken netbook variety) as far as offering a full computing environment; it is primarily a "hand-holdable media reader and communication tool". For now that does not matter much, as the iPad serves a different, more portable, hand-holdable "desk-free" niche, but I wonder what other similar one-piece "slate devices" we will see this year, probably running "Window 7 Mobile" with the option of Linux. How the race will go between iPad Apps and Windows 7 Mobile apps? How important will multi-tasking be, (absent from iPad for now), and will it be added to future iPad OS versions? The iPad's processor is not the same ARM processor as in the iTouch, so could easily have been designed with multi-tasking in mind.
