Wal Mart carries brand name PCs..the little E-Machines are made by HP.
Same ones sold at Best Buy..etc.
Both sell the standard brands: Dell, HP, Gateway..
Get a small one and install biger hard drive and more memory and you should be ok..
All stores have good computers..but..IF it breaks, where are you going to take it?
I think with WalMart it gets shipped back to plant.
Best Buy..they want you to bring it back to them (danger , danger...)
Same with Office Depot and Staples.
I bought a simple $400 e-machine from Best by for my 12 yo and have never had a problem with it!!
