Hey guys, I've had my PB 15'' 1.5Ghz as my only computer for a little over a year and its been great. However, I find the powerbook to be a bit too big to lug around campus and lacking sufficent real estate when at home. I plan on selling the PB and upgrading to either A. macbook + 23'' ACD or B. 20'' iMac. A portable is not a 'must have' but I do really used to having the portablity, however; the imac option is substantially cheaper (when you include the accessories you need w/ a portable i.e. extra battery, mouse, etc.) I also don't like having to plug in/out all the cables everyday to use the monitor. I also really like the imac's form factor. I think I like both options equally, so my question is which option do you guys think is a better value? And which options would you guys choose and why? Thanks!
