In terms of how I would use it I agree with the comments above. Its a great 'couch potato' bit of kit.
But I will go with DoubleT I will wait for the a V2 or V3. I think Apple will approach it in the same way they do the iPhone, or any other product, with upgrading cascading down as the initial interest wains.
The problem is I think these upgrades are already there ready but as with the iPhone they are being held back to maintain continuity of sales etc. The comment by Red will I am sure be adressed very soon after first release. As with other issues raised after first release.
So much as I want one and welcome its arrival I will wait... not too long but long enough to take advantage of an improved/upgraded version.
