It's almost like a real tablet PC, but without a keyboard. And a weak processor, no multitasking, fewer applications, a smaller hard drive, fewer accessories, a less durable design, no support for flash, a smaller display, lower resolution, and a non-replacable battery.
Picking a few nits.
The A4 is at least comparable to other processors in this class of device (including netbooks).
The OS does support multi-tasking, I can listen to music while doing all sorts of stuff and mail is retrieved in the background also. Apple has chosen not to allow non-native apps to use this capability. Tough call, it keeps the app in the foreground much more responsive, limits problems caused by poor/lazy programming, works well with the user interface design/philosophy but will get complaints from "techies" who want multi-tasking.
Similar situation with Flash. Flash is a proprietary solution with a horrible reputation, it chews through more CPU cycles for a lame animated add than I need to run a full up airplane simulation with hi-res visuals. It is annoying to miss out on some of the useful content that uses Flash but I don't miss the lame adds that seem to have sprung up on every other website. Personally I think Apple should have considered some sort of opt in for Flash but they probably didn't want deal with the problems that come with it.
The less durable design thing is interesting also. The iPad has very few moving parts compared to a netbook (or Kindle), and very few user accessible bits so I would actually expect it to have a very high Mean Time Between Failures (MTBF) compared to those devices. If you drop it, it will probably break, but so will a netbook etc.
So much for debating based on the specifications. The only real test is a field trial. I'll withhold judgement until after apple introduces the next generation unit
and I can get to play with one for a while.
