I prefer quality wp over smaller file size. On my work puter, I have a nice collection of walls to cycle through...either from WC or my own photos. At home, I have used the same wall for years...just a simple tiled bmp that makes my desktop look like a tapestry.
As far as connections...at home it's 512 DSL...at work it's T1, which incidentally is slower than most dial-ups (for web browsing), mainly due to the fact that most of the bandwidth is dedicated to data transfer

....so, for once I can say my home connection is faster than my T1 line at work!
