For $2200, you get 8GB of RAM, 1GB on GT 650M, a little more powerful processor and 256GB of SSD. On top of that, a much better resolution. For $1800, you only get 4GB of RAM and 512MB on GPU. Upgrading to 8GB of RAM is a no-brainer, so you're gonna spend $100. Upgrading the GPU to 1GB (imo 512MB is insufficient) costs another $200. Which still leaves you with a crappy 5400 rpm HDD and a much worse resolution. For normal users I think MBP 13" or MBA 13" is a much better option, and for power users rMBP is much more cost-efficient, at least until Haswell Pros are released. Am I right?
