I cannot justify the retina, sure it's pretty but the soldered on components? NOOOOO WAAAY. I was thinking of getting the 2.3ghz base 15" model with an anti glare screen (or is the gloss upgrade ok, thoughts?) I'd then replace the 4GB RAM with a 16GB set, the 500GB HDD with a 256gb (or 512) SSD. Is it also worth removing the optical drive for a 1TB HDD? Is it possible on MacBooks to have the OS and program's on the SSD and then most other files and media on the HDD? Thank you!
