Composability is what makes something greater than the sum of its parts. The iPad, I found, is so constrained as to be useless. I know of very few people who are still using their iPad regularly after 6 months or so precisely because of this (and the star trek wow factor has worn off). Ironically, composability is why I still carry around a 15-year old TI92 calculator instead of an iPad, even though my peers look at…
How many of those people you know with iPads are what we would call normal people? I only ask because it seems to me that most of them wouldn't mind at all that one couldn't be productive on the iPad since surfing and a few games are mostly what they use it for.
It seems to go like this:
1) They bought it with a purpose in mind but it didn't work quite as well as they were hoping (khan academy, mapping, general use, recipes in kitchen, streaming video).
2) The games last a while but they are mainly novelty rather than immersive or lasting so it's back to the XBox.
3) then the web browsing gets frustrating as streaming video is choppy over WiFi and impossible over 3G and "what do you mean flash or java doesn't work" - I can't play facebook pool.
4) then the keyboard becomes frustrating when they try and do real work because it's not tactile.
5) then they switch back to their laptop when they have to do something like mail merge.
6) then the ipad goes in a drawer, followed by ebay about 2 months after they find it again.
I've seen this so many times across about 12 ipad owners now. 20% "software dev". 40% "tech enthusiasts". 40% "joe average".
Bear in mind this is just my observation.
