Got it in Feb 2008. 2.8 GHz, 4GB of RAM, tons of space, and still fast with a lot of things. Bootup and shutdown time takes less than 15 seconds with that SSD. It's used for my heavy (very heavy) photoshop work, audiophile listening (through digital out), and even making music. It is a workhorse, but I think it's nearly time to upgrade. So I'm just about to get the 15in rMBP with 16GB RAM. No need for a harddrive upgrade, as I plan on still using the ones from the Mac Pro that has all the music and everything as an external backup. So the question is if it's worth it to keep the tower or will the rMBP be faster in everything so it's really a redundant machine? Yes, sometimes I go mobile, but with NAS, I can be on any computer and get any files I need. the rMBP just happens to be the first time I'm ever looking at a notebook as a possible desktop replacer.
