Toshiba top end were good, I don't know about today I still have Tecra 8000 it might be old but it does wireless very good. I got a couple of SPro ones too. Those were built to last and yes they did I like Compaq P V2000 Series. Most popular even with AMD 64-bit CPU and 2GB of RAM. You can get Duo cord now and 15 to 17" widescreen bright view gives you near HD clear screen technology.
It's funny if you go to Wal-Mart, Staples, Compusa, CCity, Costco, Samsclub, they all have the same model I've mention for all types of prices. Wal-Mart would be your best bet, then Staples have some crazy deals. The clubs are also good too.
If you get a laptop look for:
1 to 2GB of RAM standard
120GB HDD
DVD+-RW DL /CD-RW Burner
Wirless LAN
Wired LAN
Bluetooth
14 to 17" Widescreen HD Bright View Screen
12 Cell Battery most come with 6 Celll you can add another battery. This way you get more that 6 hrs and plus 3 hrs.
Right now am on DELL D610 I use at work, the battery is going so much for 3hr and the Centronio CPU from Intel.. More like 2 hrs battery life..
D620 is good
also D820 is also good... Thouse are Widescreen duo core CPU from DELL...
