Congrats on your purchase!! I am also going to get a Mac, but I need to replace an aging desktop. I'm looking at the Mac Pro desktop--lots of room for future expansion, but like my cars, I like to keep my computers going for years to come. I am looking to replace my seven year old Pentium 3 1GHz Dell computer which is maxed out at 512MB of RAM, though its been modded up with two huge hard drives, LCD 19" monitor, DVD-Dual layer burners, etc. However, the programs are getting bigger and I am at my limit with memory with the Dell. I am sure my P3 Dell desktop has more "Miles" than SG's X5!!
The opposite of SG, I already have two nice late model laptops. In fact, I still love my 2.7 lb ultraportable Sony laptop with a built-in DVD-dual layer burner (which is unheard of in the ultraportable laptops) and battery lasting for over 6 hrs!!
I'm waiting for Leopard to come out and get my dual 3GHz processors!!
