Other than that I'll repeat myself and say - you can add memory later, use your budget now on the stuff you CAN'T upgrade later.
MacBook (which is available in only one size 13'') and MacBook Pro 13'' both has same amount of pixels. In fact, both have exactly same specifications except RAM, MBP has 4 GB & MB has 2 GB.
By amount of pixels, you mean higher resolution, right? Like 1280 by 800 will have 1280 * 800 pixels? Both will have same 3-4 resolution options as mentioned in another post by Marc, I guess.
