QUOTE: You can walk out of Walmart with a bag of cat litter, a bottle of ketchup, and a serviceable dual-core notebook with ample hard drive space and still have only spent around $600. This has made hulking towers, and even mid-to wer PCs, a less attractive option to the mainstream shopper who just wants to hop online and fire off a few Facebook updates, but this isnt without i ts drawbacks, namely heat and ergonomics.
