Anyone seen the new HP Envy x2?
Starts at $799, but by the time you max out the CPU, give it 256Gb storage and 8Gb of RAM it climbs to over $1200.
There are a few nice points, the keyboard is included (still a major bug bear of mine, the tablet that can replace your laptop when every laptop comes with a keyboard) and is also bluetooth so you can disconnect, rather nifty, and given the space in the connect area of the Surface I cant see a reason for them not to do this.
Its fanless.
The pen has a home.
