I'm running a 15" Early 2011 2.3Ghz, 256GB Crucial M4 & 128GB OEM Samsung SSD in the optical drive, High-Res screen, and 16GB of Crucial memory. I mainly use my laptop for web-surfing, light programming, gaming, and a WHOLE lot of legal research for school. I couldn't be happier with the performance, this laptop is a BEAST! I've also got a 2011 13" i5 sitting on my desk at home with the standard 320GB 5400Rpm HDD and it's an amazing laptop in it's own right. I love the form factor of the 13" Pro's. They're just the right size. I'm debating on purchasing a 2010 11" Macbook Air or a Transformer Pad for a compact carry anywhere laptop but my iPad works pretty well for that purpose so I can't justify pulling the trigger just yet. The Transformer Pad Infinity's sound pretty awesome with the new Snapdragon S4.
