. . . aren't they suing Wal-Mart ?? Acer may have built the lap-top, but the shop stocked and sold the device at that spec. If we go with the assumption that someone shopping in Wal-Mart expects things to work as advised by the little sticker, then the fault lies with Wal-Mart for stocking something that wasn't fit for the purpose advertised.

If they bought direct from Acer, that would be a different story.

For example, if they bought a pint of milk that turned out to be contaminated/off/inedible, would they sue the dairy or Wal-Mart ??
