Khmm, khmmm,, only one thing to add to all of those comments - if you want real thinkpad, go for T-series, BUT NOT THE SL-series (they are now replacing it with L-series)!! There's soooo many users of SL 400, 500, 410 with their left hinge broken!! I personaly own 3 x SL 510 and they're "like some" better than those, but there's also few people around lenovo-forum with their hinge broken..
So, I'm not sayin anything against ThinkPads,, they are realy great,, almost undestroyable, just this "low-end" thinkpad series isn't anything better than any other usual laptop.. STILL they provide some unique features you can only find on ThinkPad.. So, if u're not planning to "move" your ThinkPad a lot,, I sugest to go for L-series (or SL if they are still on sale at your locals)..
Cheers, and visit lenovo forums for more details if you're thinking about purchasing ThinkPad.. You may find interesting suff out there 😉..
