Hi everyone, I really couldn't resist the urge to start a new thread. I have searched and seen similar comparisons/decisions but my situation is a little bit unique. I'm an mba student, I have a windows laptop I bought a year ago and I wanna switch to a mac because even though this laptop has 4gb ram, its processor is weak and I'm sick of programs not responding- even firefox stops responding with 12 tabs open when it's the only program running. I don't do heavy photo editing. I open multiple simple applications at the same time (outlook, browser (15 tabs open at the same time), skype, some music player, word, excel docs). My current pc can't handle this. I barely can stand slow computers- the main reason I want a new machine. I need to buy this pc in less than a month since I'll be leaving us till january and I don't wanna buy my mac from UK given the price different. I'm considering 13 inch base and making a ram upgrade later, also 15 inch is appealing but I'm not sure whether I should spend the extra $600. I'm a student and I can use this money for something else. I have looked the new macbook air but I didn't like the missing of an optical drive- I use it every once in a while and currently I don't have a wireless connection at home, I have to use cables to connect for at least one more month. I can wait for 6 months for the rumored new design etc but it will be painful given my current pc's situation and I can always give my old pc to my bro. so if I end up buying something new in april 2012, the one I bought now won't go to waste. So my question is what will u do if you were me? stick with the lame pc and wait, go for the 13 or 15 now?
