Perspective: I'm a computer scientist who wanted a computer that could act as a terminal (That is, a second screen) to a larger more powerful computer I have. I was looking through various 2 in 1's and decided on this based on some independent research I did. I'll break down a review of this laptop and the software needed for it, not of WIndows 8.1 or anything of the sort.
I'm not the sort to write a long review going over stuff you can figure out from watching any promotional material, so I'll be direct as to why it wouldn't be 5/5 stars: The use of a HDD instead of an SSD as the basic harddrive of choice. In this day and age, and especially given the kind of device this is, the speed of an SSD is a must.
I put in a 128GB Sandisk SSD, which fits the needs I had for it perfectly. If price isn't an option (ANd eventually I intend to do this myself), I would recommend Western Digital's Black2 harddrive, which contains a 120GB SSD and a 1TB HDD for storage. It'll give you the best of both worlds.
Oh, and for perspective: I looked at 2 in 1's within the $500-$800 range, including Android tablets. For the price, this gets you far more bang for the buck, even including a replacement harddrive. Highest screen real estate (All the rest were 10.1-13.6 inches), acceptable resolution (There are higher resolution devices in this range, but with the smaller sizes they're less usefull), acceptable specs (Not the greatest, but for your standard uses (Even including my non standard use) that shouldn't require top specced devices, it will more than fit the bill), and a nice way of doing the two in one.
