i used macbook pro for 32 months without any problem!! i do heavy graphic programming a lot of pent-testing..and it worked fine... i managed to put 900 battery cycle counts in 32 months(open almost 18 hr a day)still works fine except battery life has dropped.. if you just want to use it for casual purpose it's definitely worth it... i recently switched to u410 for more better specs..since money was an issue for me..deff worth it if money is not a concern...
