I have an Acer D250-1924 Netbook which has Atom N270 Processor 1 Gb DDR2 SDRAM 10.1" CrystalBrite display 250 Gb Hard Drive Windows 7 Ultimate currently installed (originally came with Windows XP) 6 cell battery (currently the battery yields between 4 and 5 hours, depending on what programs you are using at the time, if you are using wireless, etc. - it used to go to 10 or so. It has built-in features: a. Wireless G b. Bluetooth c. Ethernet RJ-45 Network Interface Card (NIC) d. Stereo sound with built in speakers and headphone jack e. Microphone and Microphone Jack f. VGA out (for hooking up External Monitor) g. 3 USB ports h. SD / Memory Stick card reader i. Touchpad j. Kensington Lock jack PM me for any questions. This has served me well. It originally had Windows XP and I put Windows 7 Ultimate on it. It also originally had a 160 Gb Hard Drive and I upgraded it to 250 Gb. This is a great little net book. You will need to purchase an external DVD/CDROM drive to use discs (including install discs for software). I will throw in the one I have as part of the deal if you pay $175 instead of $150.
