Hi all - I have a 2.53gz 2010 MBP with 8GB ram and an HDD. So here's my dilemma. I'm a graduate student in Neuroscience that does work with brain imaging and frequently uses ram intensive software (i.e. Mango) and virtualized linux environments. Frequently I have many apps running concurrently. I'm getting significant lag on programs like Powerpoint and the computer is just generally not very snappy. My lab has offered financial support to upgrade to a new computer, however I believe I could get 2 more years out of this with an SSD and new battery. I have 6 years in the program so waiting for the upgrade may be a better approach. Thoughts?
