iFixit posted a teardown of the Microsoft Surface Pro tablet

It's a laptop! It's a tablet! It's a lablet! It's…it's…Microsoft's Surface Windows 8 Pro, and it's about to go down on the teardown table.

Microsoft Surface Pro Repairability Score: 1 out of 10 (10 is easiest to repair)
The battery is not soldered to the motherboard, so at least no soldering is required to replace it.
The SSD is removable — but you risk killing your tablet by trying to open it.
There are over 90 screws inside this device. We're proponents of mechanical fasteners, but this number is a tad crazy.
The display assembly (comprising of a fused glass and LCD) is extremely difficult to remove / replace.
Tons of adhesive hold everything in place, including the display and battery.
Unless you perform the opening procedure 100% correctly, chances are you'll shear one of the four cables surrounding the display perimeter.
