I've been using my husband's early 2009 era MacBook Pro model which has been having some problems. In the last few years he has upgraded this machine to a solid state drive, and increased the memory from 4gb to 8gb. It runs ok, but there are some motherboard related issues (some random shut downs), and I'm going to be working from home more, so I think it's time for a new machine. Aside from general word processing, and browsing needs, I need be be able to run Microsoft Remote Desktop to log-in to my work server and work remotely (accessing files, working with spreadsheets, doing some database work) through there for extended periods of time. Right now when I'm running it off the 2009 MacBook Pro, and I've found it to be slow, though I can't tell if that's the server or the computer. I want this to last for several years, so in either case, I'm looking to max out the memory since upgrading memory down the line isn't an option anymore. Which seems like a better plan, a 1.3 ghz processor, 512gb Macbook with 16 gb of memory (around $1800) or a 13 inch 2.3 ghz processor, 256 gb Macbook Pro with 16 gb memory (around $1700)? Thanks!
