Heck, most houses I get into don't even have REAL hardwood, they have the cheap ass laminate junk. When you catch it just right in the light, you can see the dimples and cracks from where some lard ass was sitting on a chair with small legs, or a dish was dropped. :roll:
And with that said, I had top of the line Shaw cut pile carpet installed in my living room 3 years ago, and it looks like crap! Of course, I don't live in the Taj Mahal like some of you guys, so I can only arrange the furniture so many ways, but even at that, when I move the furniture to clean, the shade difference is night and day, and it's nice and soft, where the main stuff is crushed, and discolored. Never again will I put carpet in a main area. Like Stevie B, I'll put it in the bedrooms and I'll do the stairs, too, but that's it.
At least with the real hardwood, you can refinish it and make repairs, unlike the laminate stuff that's just a throw away item. Next time I'm doing it right...going to put ceramic tile all the way through on the main level. With me having dogs, I couldn't imagine having hardwood, I can just imagine the finish getting messed up in no time. Plus you have warping issues due to humidity or water somehow making it's way to it. You have none of those issues with tile. Dog claws? Not a problem. Water? Big deal. Urine or crap? Just a wipe away. If you should happen to crack a tile, very easy to cut it out and replace. Replacing a plank of hardwood in the middle of the floor. PITA!! Tile is the way to go. Just keep it sealed and your problems should be next to nothing.
