@troubleMoney before i got this specific model i just didn't know what was so special about them, other than being solid machines aimed more towards business work
now i'm pretty hooked on it, but take into account i only speak for this specific model, the 2007 x61t, and the earlier IBM forays (butterfly keyboard) look awesome, but i do think they're a bit overhyped in the foss community just because someone wrote a custom bios for it
@squirrel I like them because you can actually get into the damn things with a minimum of fuss, if you need to switch out a component it's a few screws and you're done rather than having to spend quarter of an hour prying the damn thing open
Also, really, really cheap second hand and solid enough you don't have to worry about it
