Back in Dec I was looking for a new Laptop to replace my aging Macbook - I knew I wanted dedicated graphics to game (turns out I missed that more then I thought), and an i5 processor. 13" or maybe 14", not 15"
The MacBook at the time started at $1600 I believe if I wanted dedicated graphics. Instead I bought an Acer (I know I know) on sale for $700 (Canadian Prices) - 6G RAM, 750G SATA, 13.3", thin, no optical drive, camera, i5 CPU, nVidia 540M that has played everything I've tossed it's way. Regular price was $999.
If you can show me a MacBook (And now with the new ones, maybe you can) that give me that for $700 - please match the specs up, all the specs - I may honestly consider buying it. For Dev I'd like to target OSX, but not for that price. I took a quick peak, and looks like if I wanted dedicated GPU I need to get a 15" (or possibly a Retina starting at $2100, didn't bother to look at those).
