I got the sh1+s with dell couple of years ago and bought some Lenovo T series LTs , only beef so far is the rubber feet came off mine. Rock solid performer and good price.
we are on a global pricing program so the prices aren't bad ... and the 2-3 times I've had an issue (always user ****ups) they are there the next day with new everything required - motherboard, screen etc...
anyway the only Lenovo models acceptable is i3's'.....
