The XPS proves to be a real jack-of-all-trades in routine use, but has to accept clear deductions when it comes to battery performance.

Sorry, but I have to object to your comment about maintenance on the XPS 12. All you have to do is unscrew the screws on the cover and lift the lid. It is also easy to remove the battery, so easy in fact Dell have released a http://topics-cdn.dell.com/pdf/xps-12-9250_Service%20Manual_en-us.pdf (http://topics-cdn.dell.com/pdf/xps-12-9250_Service%20Manual_en-us.pdf) service manual on replacing things like, the wireless card, SSD, camera, etc.
I agree...
Obviously you have to be careful.. it is delicate electronics and the parts are very small.. but anyone with any common sense could easily replace the disk.. just undo two screws, pop the screen off, take out the old SSD and insert a new one.
