Hey Ive been using a black macbook for about a year and i love it. Anyway Ive been thinking of buying my girlfriend a powerbook off craigslist so i can throw her dell out our window. Since im only familiar with leopard and so isnt she from using mine I want to make sure it can run leopard decently. What are some specs that are recommended? How easily upgradeable are the powerbooks, ram, HDD and i think i have read about cpu upgrades but not sure. How much should I be paying for a powerbook decently equipped so i dont get screwed over. Any help, tips, would be greatly appreciated. Thanks guys! I found a 1.25ghz 12" powerbook on craigslist for $280 http://boston.craigslist.org/nwb/sys/1142385875.html thanks again for any tips!
