Im looking for powerful 13 laptop to replace my old PC. Ill be using it for everyday life stuff and coding. Im really concerned about overheating. As it is said on Apples forum, new 15 MBP overheats. What about 13 MBP? Will the VAIO SB1A heat too? As it is built on the same CPU, but in addition has GPU. Another question is which keyboard is better? As I can see both have non-standard keyboards. I have never tried Mac OS X, so I dont know is it better or worse than Windows.
