As you can see, differences between the Intel Atom N280 and N270 are minor, which is expected since the CPUs are very similar. Even N280's faster FSB doesn't help much in benchmarks, as well as in real world use. I haven't noticed any difference in responsiveness and speed when using the netbooks for web surfing, e-mail checking or watching Youtube videos.
