I purchased a gen 1 version of this in a sale earlier this year, used, for $360. Lenovo ThinkPad X1 12" 256GB Tablet
It’s everything I’ve ever wanted. It’s like an over-powered touchscreen netbook and a tablet all in one. The keyboard cover is much easier to use than the fixed keyboard on my 17" laptop (also by Lenovo, but not a ThinkPad). It’s fast and sleek and small and cool and perfect for travel and home use.
This one comes with the Pen (I spent $50 to get it separately). It’s a little faster, and it’s brand new and under new warranty.
It’s taking everything I have not to buy this.
