As a professional photographer this thing is (and always will be) an "App Store" toy - nothing more.
The iPad will never have the horse power to do what pros need.
A number of the comments here ("toy," "will never do X") are more than a bit reminiscent of what many reviewers were saying in 1984 - about the Mac.
9" 512x342 monochrome pixel display. 128 KB RAM. 8 MHZ Moto CPU. 16 bit. (Note that's "KB" - not MB, let alone GB - and "MHZ" not GHZ.) No HDD or on-board storage of any kind other than its 64K of ROM. The OS, apps and files shared the use of a single 400 K mini-floppy disk. Two non-standard serial ports. The original keyboard lacked arrow and function keys, and had no numeric keypad, enraging some potential users. And it went to market with fewer native apps than the Xoom.
And if you go back and look at MacWrite and MacPaint and compare them to where that "toy computer" and its apps are today (along with all the Windows computers which, uhhh, adopted its basic interface and input metaphor), and what it does.......
...i.e., all the types of tasks people here are saying can only be done on
its current iterations, and "never" on the
new toy...
...all the while (albeit with a hiatus in its middle years) remaining under the firm control of the same visionary leader someone here has labeled a "charlatan" and "aesthete"....
...and I've enjoyed watching it all happen while the naysayers have foamed at the mouth and gnashed their teeth at each and every new Apple release - even as Macs now hold an amazing 90% share of the premium (i.e., money-making part of) the PC market. Some toy.
And lest some of you have forgotten, some program called... ...what was it, oh yeah, "Photoshop"... ...was originally released on this "hopeless" platform. (As were Pagemaker, Illustrator and QuarkExpress, e.g.)
We're four years into iDevices and only ONE year into the iPad era. The New Yorker had a cover created on an original iPhone within months of its release. A somewhat major artist released a video on YouTube produced on an iPad 2 with iMovie and GarageBand within a day or two of its release.
What will these device classes (and their successor innovations) be capable of in 3 years? 5? 10? 30?
Perspective, people. Vision, hope, creativity, engineering, a willingness to jump off (calculated) new cliffs - and perspective.
Some'a y'all oughta' go develop some.
