I had a post a couple of days back asking about making a choice between a PC (3.2GHz with 2Gig RAM) and a Powerbook (1.67GHz with 2Gig RAM). I already made the switch from a PC to a Powerbook and am very happy about it. Powerbook is a little slow when it comes to opening software applications but overall it functions smoothly. I noticed a major difference when I opened a couple of applications at the same time with out any problems. I was amazed to see that. I could in fact play different music pieces made in different programs like Logic, Reason, Garageband etc at the same time and there wasn't even a smallest glitch. Oh and the OS is what a pleasure! It's like having a bmw/mercedes, a luxury car! Now, my question is, if I want to have more processing power, can I use a mac mini with the Powerbook making use of Logic node? How much of a difference would it make? Has anybody tried this for a while? I'm thinking of buying one since it's cheaper here in US before I move for a while in Asia. Also, which one should I be looking at and should I be upgrading memory or harddrive in it?
