Netbook is 9 hours battery life, bluetooth, and SD reader.
Newegg.com - ASUS Eee PC EPC1000HE-BLU002X Blue Intel Atom N280(1.66GHz) 10.0" WSVGA 1GB Memory 160GB HDD Netbook - Netbooks
My macbook (two years old and it's laptop) is more than 5 hours.
Now newer Macbook Pro is more than 7 hours battery life at Nvidia 9400m. No, Your PC laptop can't do that.
Apple - MacBook Pro - Features - Now there?s even more innovation.
So I like to use netbook for heavy travel, class, and lab.
