i bought an ipad and use it daily, i do not have the 3g version just the plain old wifi. one thing that i have noticed is the amount of people saying "what are you going to use it for" or "what a waste of money". the thing is, i do not need it, i just wanted it. Like text messaging years ago, people (myself included) said 'who is going to use that". It seems to me that people want on but have to justify having one, and if they cant the react by criticising those that have bought one.
i have to say that i use mine daily and its uses are only going to get better. its in my lounge as a photo frame between where my wife and i sit. you can pick it up at any time and browse the net while she (or me) are watching shite on telly and surf the net. I take it to bed and read many of the free books online (titles that you know) and you dont have to have the light on to piss your partner off, then there is BBC iplayer to watch telly whilst relaxing on the sun lounger by the pool in the garden, or if telly is not your thing read the independent, the mail the sun or whatever you read online FOC. in the garage i look at the how to guides online for stripping down or rebuilding something...... i could go on and on (i have a bit already, i know) but to me i feel that im using it more and more
oh, and as for the iphone - i had one for a day and sold it (too brittle for me) however, the new bullet proof model is next on my list (when i upgrade). It is completely different and very much the same. Try surfing the web, reading or watching a film on the ipad compared to the iphone, the iphone is a great compromise because of its size
Oh and then there is the ipad / laptop debate - its nothing like a laptop - dont even go there...
