Let's talk about Dells.
Last year when I working in real estate (short-lived), I bought a Dell b/c I needed Windows and there was no intel/bootcamp world yet. I used my Dell laptop for 10 months before giving it as a gift to my mom (60th b-day) and she needed a new laptop (she too is in real estate). Now, it was not a bad machine. I used it quite a bit at home even though I had my G4 tower b/c I could surf the web on the couch while watching tv. But it was Windows, and no iLife or anything else OSX, except for iTunes which I could play to my stereo (airport express) sharing my G4 library. For most everything else I was on my old, relatively slower G4, why, b/c OS X (and it's only running Panther 10.3) Now I just use my wife's 12" PB which is a little small on screen size for me. I'm also about to order a 24" iMac - 2.33GHz 2GB RAM 500GB HDD 7600GT 256MB VRAM Wireless MM & KB and Applecare and probably a 8GB Nano. It will cost me US$ after discount $2,713 ($2,940 with Nano). I'm excited. I'm not complaining. Other than my Dell, my last new Mac was my G4 450 - Feb 2000. The only thing I could possibly complain about is no available Mac Pro Jr. for $1600 that I could hook to a 23" ACD. I like the aluminum. I'd even love a black iMac. But the 24" white will do. And for quite a while. Though I doubt another 6 1/2 yrs.
