I have a 13" early 2011 2.3ghz i5 macbook pro but lately have been thinking about getting the 17" pros because I got rid of my desktop. Now my macbook is the only computer that i use now. I found a used 17" macbook pro core 2 duo 2.8ghz unibody with 8gb ram from june 2009 that I am interested in for about $1100. Do you guys think that trading in the 13" i5 for the 17" core 2 duo would be too much of a downgrade? I only do the basic things like web surfing and watching movies/videos and occasionally do some photo editing stuff (nothing professional). Your advises would be appreciated.
