Windows is not the enemy of netbooks
I don't understand the complaint about netbooks being underpowered. My old Samsung N140 (Atom N280 at 1.6GHz, 2GB RAM) runs Win7 Ultimate 32-bit just fine. The original Win7 starter + crapware quickly got annoying, and I eventually replaced the 250GB(?) disk with an 80GB SSD, of which I use less than half - this improves battery life a lot and improves performance a little. I run Office including Access, statistical analysis with Mathematica and R, VBA programming, and basically all the same stuff that I run on my desktops. Yes, some operations that take 10msec on a fast desktop take 30msec on the netbook, but you usually need a timer to notice the difference.
Of course, I could have bought a full laptop for the money I spent upgrading, except for two points: (1) Every manufacturer seems to supply Windows + crapware preinstalled, and there is no way to thoroughly remove the crapware and get decent performance from Windows except to install a clean copy direct from Redmond. So that upgrade is necessary on a laptop anyway. (2) Laptops are too big to fit properly in front of the next seat on a train/plane/bus, where I do much of my work.
Modern machines, even netbooks, seem easily powerful enough for the things I do. I wouldn't try video editing on one, of course, and I don't play games. My complaints are the crippled screen resolution and the fact that opening a Sammy case to upgrade is difficult and dangerous. But this line-up shows that there are netbooks out there now with reasonable screens, so maybe it's time to upgrade. (I'd still transfer across my SSD and my proper Windows, though.)
