Hi Everyone, I was wondering what you guys think about upgrading my MacBook Its specs are: 2 GHz Intel Core 2 Duo 4GB Ram 160 HD 5200 rpm (Stock) My MacBook is 3 years old now and thinking its time to upgrade, Wondering what your guys thoughts are! 1)I am thinking about either upgrading the software to Lion or Snow Leopard 2)Thinking of upgrading the HardDrive to either the Crucial M4 128GB SATA SSD or the Seagate Momentus XT 500 GB 7200RPM. The price difference is only 40 dollars but my main concern is will the SSD work well with my MacBook? 3)My battery life is getting pretty bad. Im lucky to get about 2 to 2.5 hours on it with wifi off and screen brightness on low. My Battery life is 93% with 270 cycles. So not sure what I can do to increase that. If you have any other advice it would be really appreciated Thanks!
