Hi All, This is my first post. I have a question regarding my Macbook Pro. I would like to know if i should upgrade components of my Macbook pro or buy a MBA. What i have: 15" Early 2011 Macbook Pro. 2.2Ghz i7, 4GB 1600 DDR3, Intel HD graphics 3000 384 MB, 500GB HDD. It recently crashed with white lines. After researching it turned out its a known problem. It was the GPU, which i got fixed. I am not sure what the guy fixed it with and what my old GPU was. I paid $375 NZD. The laptop is extremely slow (before and after new GPU made no difference). Loading up movies, finder, system pref, chrome etc is slow. I dont do any gaming or video editing etc on it at all. All i do with my laptop (only computer) is watch movies and browse internet. I dont take it with me travelling as its too heavy. When i am watching movies its connected to my HD LED TV. So my question is should i upgrade this MAcbook or buy a new MBA. Here are my options and costs: Option1 Upgrade current Macbook pro: New 512 SSD and 16GBRAM. Approx cost $650 NZD. Option2 Sell Macbook pro. I think i can get $1000. Buy new MBA. I will prob buy 256 13" MBA with upgraded RAM. It will cost $1800 NZD. So cost of upgrade to me would be $800 NZD. I dont mind the price difference in the 2 options. However is it worth upgrading the old Macbook pro. How long will it last me? Is it too old to upgrade? Or should i just sell it and buy the MBA. The GPU replacement has 3 month warranty from the shop. So i thought its best to sell it now before it breaks again. Apparently its a well known problem. My main usage is watching movies, videos and browning internet. I travel nationally quite often. Short flights (1hr) and usually day trips. If i had a MBA 11" i would love to take it onboard with me. But no way i would take my 15" Macbook pro. Too heavy. Taking it with me while travelling for work is not a priority. Any thoughts suggestions would be appreciated.
