I'd like (when it is a bit more finely polished) to see AROS running on one of those hand held touch screen devices personally.
I see the X1000 as an Amiga OS 4 machine and that's what (if I see it being worth while) will buy one for, that being to have the best OS4 machine possible...
...though we'll see, it all depends upon the developers.
One thing the Amiga (all variants) could really go for is some original apps. I LOVE the ports, keep them up, but I miss the old days when you could go through Aminet and find all sorts of exotic software that was very original, unique, and only on Amiga.
Showgirls I feel would be one great example of such software.
In regards to OS4, that extra processor once again could be the key...
Of course that might tick off OS4 users that don't have an X1000, having software that their hardware don't support. Then again, if the X1000 becomes that good, then it would also serve as incentive to purchase one.
