I bought my 15" MBP in August of 2007 and since then have been using it EVERYday for graphics/photo/video editing. It has been well loved, making it through life in a college dorm and even through being dropped(oops). My question is how long will this badboy really last? How long do you think I can keep depending on it to get work done? I am going to be starting a graduate program in January, in which I will be working a great deal on my laptop for more graphics/photo/video editing and programming. I am contemplating whether it's necessary to buy a new MBP. I am a little bit afraid my laptop won't make it through another vigorous year of work. Am I being over cautious? How long does a well loved MBP usually last? I upgraded to Lion recently and my adobe suite(cs5) seems slower, and things like iphoto/Photo booth crash consistently...not sure if this is just Lion? Or if getting a newer MBP would help adobe run smoother? Other info: -Over the summer I put a new hard drive in for more space(750GB) -The only other issue I have sometimes is that my internal speakers quit randomly. This usually is resolved by restarting my computer. -I'd like to save money, and use the money for a new laptop on other things I need for the program(like a DLSR), but I realize that having a good laptop is important for my program too! advice?
