I have been using PC for almost 10 years and really got tired of all the problems related to windows. I have been considering switching to mac for several months, but I still have some questions about mac and wish anyone can help me a little here. - "The Hardware problem" As we know, the general ram we use for PC is 2 GB. But for the macbook, it is 1 GB. I really doubt whether it is enough and it costs 150 dollars to upgrade to 2GB from apple. ~~~~. Is there anywhere else I can buy the ram (I am not sure whether the ram is specific for mac) ? About the HD, I have no idea what the 80 GB means to MAc. The pc I use at least has 160 GB. - "Software problem" OK, the Office I use was downloaded from internet(dont ask me whether it is piracy). I am just a poor student and cannot afford the price. If I switch to mac, i dont know where to get it and I just saw the price of the new office for mac, 199$!!!!!! -"Rumor" Many people have told me the "Jan 15". Should I order it right now or just wait until Jan 15? Is it possible apple upgrade macbook anytime in the near future?
