Should I get the 21.5 inch iMac or the 13 inch Macbook Pro? (Or something else?) Looking for a new machine to be our primary home computer. Other than basic document creation/ blogging/ web-surfing, the main things we plan to use it for are: photo editing and organization, home video editing (and DVD burning for older relatives), Skyping, and managing our music and video library. Budget maxes out at $1500 (thanks, tax refund!)--but less is better.

Right now, Apple has a couple of refurbished options that look good:


Refurbished iMac 21.5-inch 2.7GHz Quad-Core Intel Core i5

Other than weighing portability against bigger screen size, is there any reason to prefer one machine over the other? Are there additional considerations we haven't thought of? And is there any reason to avoid refurbished machines? Thanks!
