I feel like a time clock is ticking for my MBP[even typing this post lags]. My year old 13" uMBP has given me PC like problems and lags tremendously. Sometimes the start up screen [Apple logo with the moving circle] NEVER subsides even after hours on. The beachball comes up ALL THE TIME [not just wish browsers], and I primarily just use internet browsing, word processing, media [iPhoto and iTunes] and Skype. I've transferred all my important files to an external harddrive, I've taken it to my university's tech services [they did only short term fixes], and I don't have AppleCare. I can get a new HD, which essentially makes the computer new again. Should I get the regular 250GB HD, or should I invest the money in a brand new SSD HD [60-80 GB], but put all my big files on my external harddrive? If I get a new SSD, does anyone have any recommendations?
