I apologize if there is another thread for this topic, but in the last couple months I've decided: - that the existing model (w/Sandy Bridge) is plenty enough of an upgrade from my24", late '08 3.06 Ghz, 4GB Ram, 500GB HD, and wanting good speed for just web browsing, email, some photo, lots of movie streaming, and occasional music on Garage Band. I am so ready to pull the trigger on a new 27" 3.4 Ghz, 4GB ram, 256 SSD. My question is how many would get just the 256 GB SSD? After 4 years I've only used about 2GB of storage and a lot of that is stuff that I'd gladly give the heave-ho to. I'm sure it's enough for my use. I figure that upgrading to 3.4 Ghz, and SSD would not only give me the most fun (efficiency) but if I had to, easy resale value. Is it true that once you get the 256 ssd, you can't upgrade to more space?
