I have personally never held a Pre in my hands before so I don't know first hand what it's like to use but in the videos on YouTube I liked what I saw and would certainly be interested in trying WebOS on my N900.

I think that there are many good things about the OS and it could have been or maybe can still be one of the best mobile OS on the market.

The only downfall is the lack of applications for the platform and it's probably the reason developers don't really seem to be interested in porting it to N900.
