Personally just got a Macbook with 2.16 GHz processsor, 2 GB of ram and 160 GB drive. Need it for work and must run Access so I decided to Bootcamp it if me or any other user must run windows. I installed Parallels running the bootcamp's image virtually for when I just need a quick dip into windows. So far happy with the set up and the only limitation is I can not use the the suspend mode in Parallels as it could corrupt the bootcamp image.
It replaced a powerbook G4 with 17inch monitor. Major speed difference. Would have loved a Macbook pro but could not justify it for my needs.
