Regular readers will know that I now use a Lenovo X200 for most of my computing needs. It has Libreboot installed and I run Trisquel 7 GNU linux on the laptop. This laptop is perfect for linux, all of the hardware including the updated Atheros wifi adaptor have open source & free drivers available & the machine is truly 100% my own.
The laptop itself is still fairly powerful for an older laptop with an Intel® Core™2 Duo CPU P8600 @ 2.40GHz dual core processor and upgraded ram to 4GB it really is a good mobile workhorse. I only paid £50 for the laptop in September & I installed 4GB of ram I had in my desk drawer from an old Macbook upgrade. I also updated the Intel wifi board to an Atheros to allow me to run Trisquel.
