Here's my macbook pro configuration details: 2GB DDR3 RAM, 160HDD, Core 2 Duo 2.26 GHz Processor. I bought it sometime in September/October 2009. It currently runs Lion and it's rather slow. I'm planning to go ahead with the OWC Data Doubler+SSD and use HDD to store files. If you could kindly give me your suggestions and opinions, it would be great: 1. Would i face any issues with the configuration of my macbook pro? 2. Would i be able to use any brand of SSD? i'm thinking of 128GB Kingston or 120GB Samsung 3. My most frequently used apps include Google Chrome, Safari, Photoshop CS4, Text wrangler, MS Word, MS PowerPoint, VLC among few other apps. And if you are using Data Doubler, what do you think of this product? is it worth getting SSD?
