iFixit wasn't a fan of the original Surface Pro's poor serviceability, and its opinion isn't changing much with the Surface Pro 2. The fix-it-yourself shop has rated Microsoft's newest tablet a 1 out of 10 for repairability after finding that many of the previous model's challenges still exist. The slate's display is very difficult to remove, and assemblers have glued numerous key components (including the battery) into place. More than 90 screws fasten down whatever's left. As iFixit notes, the Haswell-based processor is the biggest difference here -- virtually all of the battery life and performance improvements come from the CPU upgrade. If you're curious to see exactly what has changed, or just want to delight in iFixit's suffering, you'll find the full teardown at the source link.
