An anonymous reader writes: Recently, I have been bit by a computer repair on an emachines computer that involved a system board replacement. Though this was strictly a repair, not an upgrade, neither MS or emachines will provide for activation of the system. Why should a user have to purchase another copy of XP after repairing a computer? The systemboard is listed on the emachines website, but costs 4x what an off-the-shelf board with the same chipset/capabilities costs, and furthermore is not actually available. The emachines rep even said repurchasing XP was my only option. This seems to me patently unfair and of questionable legality. Is it possible that there are enough disgruntled consumers bit by this problem to generate a class-action lawsuit?
