Why does the 1000HE have a good fanbase? Price, performance, battery life, 93% keyboard size, just to name a few. If I were to pay $700 for a netbook I may as well go out and get a regular laptop that could easily out perform the N10J. It would have a faster processer, larger screen, more ram, and roughly the same graphics.

You can get a netbook such as the 1000HE for around $430 shipped, if that. Use the $270 you saved and build a budget desktop to play COD4 (assuming you have a monitor already). 2 systems for the price of 1 and the best of both worlds.
