There is no bigger Mobilepro 900/900C fan than myself. But I would never hesitate to own a Netbook Pro. Most of them work beautifully, and there is nothing like a nice big screen for surfing.
As far as those generic CE5/6 netbooks...I see them as the natural evolution of our legacy HPC devices. Since I already own every Mobilepro made, quite a few Mobilegears as well, as well as a Jornda 680/728...I made the plunge and now own one of those netbooks...and have a couple more on the way to play with.
