I will buy the cheapest one some time mainly to play chess on, read the odd book and browse the web . Any other use I can find for it will be an added bonus
When I bought my Ipod Touch I was as attracted by all the Apps as the convenience to store all my music . Six months down the track and 100 Apps later I find the only one I really use is a conversion program and occasionally Flashlight. For all its promise most of the apps do something I didn't really need to do, and are limited in what they can do and the tiny screen often makes them novelty value .
On the other hand it has revolutionized my music listening habits and really brought music back in to my life. I have docking stations with speakers in almost every room . I love what the Ipod Touch was designed mainly to do .
I expect there will be some very nice apps to utilise the greater processing power and screen real estate, so I'm sure I will have more joy with Ipad apps.
I think what cheeses off the bulk of the computing community is not how many of these things sell , but how much hype surrounds what little it can do. I can really see the niche and am not an Ipad 'basher'. I look forward to seeing how it can enrich my experience in interfacing with computer technology. Its all good.
