Well i had an interesting experience.. i have been on the 8130 for 3 days now, ran into a collegue that has the 8830 and I really disliked typing on it after getting used to the pearl. I did like the bigger screen. I would love a curve with a pearl key board.
I agree with Kelly Carter, the pearl keyboard is fast if you are willing to learn it and it comes really quickly. There is an economy of movement on the pearl. Less movement means that ultimately you can go faster. On a regular keyboard you use all your fingers so obviously you can fly on that, but the with two fingers I am finding that less is more
I never thought that I would like this more than the full keyboard but I think I do.
The screen size is a different matter. Its nice to have more screen IMO.
