bluetooth seems like a sham to me, my ex-gf father had it installed for a few uses, and he is moderately computer literate and it took him a month to get all his glitches out he said... it just seems to be overhyped in my opinion and is being eclipsed quickly by better technologies.
i use it to connect my comp to everyones phone in the house (T610 6230 and V600) its only use as far as i can tell it to transfer pictures/ tones/ games etc. . . . its only got a range of 10m so i dont see why anyone would use it for a printer over a cable? IMO it will the stuck to phones until they have wifi as standard then it will become unheard of.
