My mid 2009 MBP died a few weeks ago and I bought a Retina to replace it. My battery life was pretty nonexistent. It feels wonderful to have a battery again. I do a bit of CUDA programming, so having the bigger graphics card is nice. Also having a SSD instead of a hard drive is great. I don't have to worry about shaking my laptop when I use it in bed. I was really reluctant to spend the money since I was waiting for the next Intel chip revision in June. There will always be a better laptop in the future. I haven't had any problem with not having a DVD drive. I did buy a Thunderbolt Gigabit Ethernet adapter though. I am happy with my purchase, but it really hurt the wallet.
