I've got an older home (1930) & I've had the hardwood floors done; some in 1986 & some just last week (they were under carpet for 30+ years).
A full drum sand & refinish will have the floors looking like new.
Two of the rooms we just removed the carpets, had a very light sand (to remove the glue down carpet residue), stain, buff & fiinsh.
They're not new looking but very appropriate to an old house, we're going ot be doing some addion work so we opted for the quick & dirty solution.
If you don't want to spend a lot of bucks you could go the cheap route like we did in the two rooms. With an area rug you jsut have a hardwood border.
The condition of the floors will depend on how many re-carpets & how brutish the carpet people were. A ultility knife cross gain wil really show unless you fully drum sand.
If you remove the carpet be careful to get all the nail. tacks & pad staples up.
I'd either leave & clean the carpet OR remove & work with the exsiting hardwood. I don't really see the value of the lamiante when you've got the real thing cheers Bob
