I think the interesting question here is: when internet tablets/smartphones have the same basic usability as a netbook, which will people choose?

It's not really that clear cut in my opinion, I for one might be tempted by the incredible mobility of the smartphone, but my friend will never buy one because he finds the screen too small to use for editing documents.

So Nokia are looking to be in both of these high-mobility markets (the do define there business as mobile after all), their sales over the next few years will say a lot about where the overall trend will go I think
