After an X201Ultrabook, this was the next LenovoThinkpad that I acquired, as usual via EBay (or possibly Amazon, as refurbished laptops and workstations like the HP Z800). This is a way of getting hardware I could only dream of, at affordable prices.
I have only one T410, though I have four T420s in various states of repair (i.e. two have broken screens for example). My T410 runs Xubuntu, as do the rest of my Linux laptops (as and when I use Bertha, my Z800, again, I'll install Xubuntu on that too as I much prefer it to Gnome).
