Hi, I have a MacBook Pro 15" from fall 2009 with the following specifications: CPU: 2.66GHz Intel Core 2 Duo Memory: 4 GB 1067 MHz DDR3 HDD: 320 GB 5400 RPM I'm thinking of doing a minor upgrade, when OS X Lion comes out. I am completely satisfied with my MBP, but a little more speed using heavy applications wouldn't do any damage. I don't play any games on it, however, I work as a web developer and Aptana Studio (developing software) can get slow at times (both at startup and while running). I'm using about 200 GB of the 320 GB, without plans of using much more. What would I enjoy the most; 8 GB ram (4 GB extra), or upgrading to an SSD HDD? I was thinking of an SSD between 200 GB and 300 GB, and then saving my current HDD so I could by a USB case for it, and use for data store. If I should go with the SSD, are there any you can recommend? I've been out of the hardware market for quite a while - actually since upgrading from PC to Mac. And is it easy to install by yourself? Happy thursday!
