Software, no matter how good, can EVER substitute good hardware. This is the very reason I refuse to buy a Mac. Great OS, but no matter how good your OS is, it will never make up totally for the lack of good hardware. A good OS is more or less an addition to the good hardware. This is how I see it anyway. Intel Atom CPUs, especially the single core variety are very weak. If I were to ever get a netbook, I'd probably go with one with an AMD Athlon Neo x2 and 2GB of RAM. AMD has some good netbook CPUs that are dual core and are cheaper than their Intel counterparts.
