Does anyone have experience with designing devices like this? Why would MS (and Apple etc.) design products so that they can't be serviced? I understand you don't want to warranty devices that users mess with but there a simple ways to determine if a device has been tampered with.
This just seems like a fail all the way around to me. You would think it would be a positive to be able to advertise that the battery or drive could be replaced or upgraded (even if you had to send it in). Unless MS has some magic machine that can open these up, they won't be repairing any defective ones so they loose money on everyone unit that it replaced under warranty. They have no chance to recoup money via refurbished sales. Finally, they loose the potential revenue in selling replacement parts.
I just don't understand why companies do this.
