Shopping for a new replacement laptop for my aging Surface Pro 3 - I really _want_ to get a nice refurbished laptop, but none of the websites I looked at are able to help me pick a device that I consider would suite my needs. Would be nice to have this info: release year, touch-capable, RAM-upgradeable (max ram, free slots), HD swappable yes/no, Battery replacement available, user serviceable yes/no (service manual, ifixit link)
