Ok... so i have read in many threads that the display quality on the old models is much better on the 24". My question is, to an average user just using internet, basic word processing, music etc... (not a gamer or video editor or anything) will the difference in display really be that noticeable?? I am thinking the 20" will still look just fine, but I don't want to make a naive choice. The 24" just seems too big for the needs I have and probably also the space I am putting it in. Also, is it that hard to install the iLife 09 upgrade if my refurb comes with ilife '08?? Thoughts??
