Hey, I have a June 2009 13.3" Macbook Pro (2.26 ghz Core 2 Duo, 8 GB Ram, 750 GB Scorpio Black 7200 RPM hdd) running latest 10.8.5. My battery currently last about 2.5-3 hours depending on usage. It's pretty heavy (with the charger and extension), so sometimes I take my iPad w/ keyboard to do some light word processing/email/internet/etc. The speed is okay, but I could definitely use more (I use a resource intensive research software and do some light amateur photo editing in Lightroom). I'm thinking about replacing the 750 GB hdd with an SSD (probably around the 320 GB range). Also, thinking about adding in a new battery. Is it worth it or should I just wait until this dies to buy a Macbook Air (my next planned Macbook, but not for awhile). The MBP I have now I could see lasting me another two years probably. So basically, I just want to not need to bring my charger around and to make it faster and to see if this is worth the price right now. Thanks.
