I have a early 2009 unibody 17 inch MBP. And was considering buying a new 27 inch iMac fully loaded that someone is selling for $2000. My other choice would be spend about $500 to upgrade my aging MBP by adding a samsung 840 evo 500gb ssd and maxing out the ram to 8gb. I'm not sure which would be the better route to go. My MBP already has the bulging battery issue and I'm not sure if it would be smart to spend money upgrading something that's 4 years old. I use my computer mostly for design work. I do a low of graphic design for print and also web and some interactive and video stuff as well. Would love to here opinions on others so I can make a better choice. Thanks.
