It has been a week, and the original 'Will you buy an iPad?" thread has been very busy.
So, did you buy one?
(I did, but it is now my wife’s)
I mocked the device.
Then, on a whim, I stopped by the Apple store on Monday evening. Two minutes were enough to convince me.
I bought it with the plan of giving it to my wife since she often sits in bed with her Macbook surfing, watching Youtube, and reading email, three things that the iPad does well.
It’s looking like I might need to buy a second one, since I like it so much. Netflix is excellent. Surfing is much better than I imagined. Typing is almost as fast as with a regular keyboard.
I just stumbled on an iPhone dev course from Stanford that has all lectures filmed and posted for free on iTunes University, and I am working my way through the class, watching the lectures on my iPad. 
I’ve yet to see anything that indicated the iPad had any advantage over other devices. It seems to combine the disadvantages of a tablet computer with the disadvantages of a smartphone. I figure it should cut my typing speed in half (most Apple keyboards cut it about 20%), which makes it useless as a computer, and it’s much too big and heavy to replace a smart phone or a dedicated book reader.
You left out the “still undecided” option…
I’m waiting for the second generation which I’m betting will hit relatively quickly, perhaps even for the holiday buying season this year. It’ll be a wandering machine in our house, replacing my mother’s sorely out of date iBook, actually upgrading her ability from that, as it can’t stream media and has no functioning speakers. I imagine I might also use it in the kitchen in the manner I currently use my iPhone, for consulting recipes, which will be much easier with the larger screen.
“Bought or bought not. There is no undecided” 
I ordered a 3G iPad minutes after preorders started, but I’m still waiting for it of course. It’ll replace my laptop which I don’t really use for anything other than web surfing on the couch.
Store is out of em. I’ve got dibs on a 32 gigger due wednesday.
I put myself down as Yes, even though it’s not quite accurate. My work bought me one, got it on Monday.
So far, it’s absolutely fantastic. I love it as an ebook reader (I’m a fifth of the way through Neal Stephenson’s The Confusion). I can type plenty fast for composing email. The browser works very well.
The only complaints I have are that Mail seems to be a bit slow/unstable, freezing for several seconds and crashes at times. My 3GS doesn’t do that. I think the 3.2 OS needs some polishing, which is probably why iPhone/iPod touch are going straight to 4.0. Also, Google Wave doesn’t work at all, but that’s Google’s fault, not Apple’s. (It doesn’t work on iPhone or Android, primarily because it uses and absurd amount of memory.)
The iPad apps I’ve tried so far work nicely, but the selection is still a little thin. Most iPhone apps running on the iPad are not a very satisfactory experience. (My coworker who bought one 1st-day says a lot of games are fine, though.)
I think it’s going to be a very fun platform to develop for. The sheer amount of extra space/flexibility combined with the touch interface is going to produce some extremely nifty apps.
There’s a “no, but I plan to” and a “tried it, won’t buy”. It seems like there ought to be a “No, but I haven’t made up my mind yet”. I picked “tried it, won’t buy”, but I haven’t really made my mind up. I just don’t have any particular plans to buy one (yet?).
