I can either buy a 24" iMac or the base model 15" MBP (with only 128MB video memory). What do you recommend? I have a 12" tablet notebook currently (up until I am authorized to sell it in may 08). So if I bought the MBP it would be used primarily as a desktop machine (with my Dell 2007WFP). So what do you think? Both are quite expensive and I just sold both my macbook and mac mini (if that matters lol). I have two (maybe 3) main options to summarize: 20" Alum. iMac using the external display (2007WFP 1680x1050) 24" Alum. iMac (selling the external display) 15" Macbook Pro (8600GTM 128MB model) using external display Opinions? Alternatives?
