As befits my tendency to purchase technology once it's mature, I put my family's birthday gift towards a first gen iPad. All they had left was the 64M version, so I copped to lots of memory. I've been messing with it for a few weeks now. And I'm mighty pleased with my purchase. I mentioned my "attachment" to the technology - my friend Peter noted that "it's very sticky". Yes it is.
Mostly, I'm using it to stream movies / documentaries / tv shows (thanks Netflix) and although I'm not quite ready to kill my cable subscription, I am getting close. Netflix + Hulu might be all I really need....
I'm also amazed as usual with Apple's user-friendliness - when I synced up the device all my iPhone apps got installed - at least until I went hunting for the iPad versions of most things. No muss, no fuss.
The one app that I am really enjoying is Flipboard - it's a news reader - but it seems to glom onto just about anything (Twitter / Facebook / RSS / websites) and converts these things into a slick magazine. I've never been much of a twitter user - being put off by the links and such. But Flipboard has converted my twitter community into an amazing resource for news, articles, etc.
I am sure there are plenty of other useful apps out there to be discovered. But right now, the iPad is all that and a bag of chips.
