Interesting that HP seems to be the industrial choice (we have them at work too). At home, we've had no issues with any of our Dell's, which is what I'm on right now. We also have 2 HP's. Haven't had any issues with any of them, either. My old Compaq, however...different story.
If I were going to be doing the "family photo" thing mainly, besides an occasional movie or serious work, then I'd choose HP over the Dell. It's mainly the software piece of it anyway for the photo gallery thing, not necessarily performance. The wife likes to print out pictures and such and once the picture paper is loaded in the printer, just a few clicks and presto. Instant picture. Just an opinion.
I'm not any sort of IT system admin, but computers usually don't get slower unless there's some major fragmentation of the hard drive, running too many tasks at once, or you have some sort of virus.
