I have an April 2010 Mackbook Pro. Love it, but at times I do bog the machine down a bit. 8 gigs o'ram, so I can't expand that, and I am not really ripped up with the idea of taking out the ODD and putting in a SSD even though I have not once used the ODD. So, these are the options I'm considering, was looking for positive feedback on the options (in other words, I'm not looking for a discussion of why this option is lousy and you should only get this other one.) I rarely spend time with my dual core 2.53Ghz I-5 first gen processor doing a lot of heavy lifting other than when I start Chrome and it has a bunch of tabs to grab, or if I have a VM running. My performance issue is pretty much only memory related. Well, also my ego is sensitive being 3 releases back. LOL Option 1: Top of the line MBA - when in my last job, I had an October 2011 top of the line MBS with 4GB and the 256 SSD and the speed of the SSD often made it feel like it had a lot more memory than it did. I figure 8GB of RAM should be just fine, and I can offload some of the lost storage to one of my networked drives. Option 2: New base MBP 15, kick the memory up (is it possible to kick the new ones to 16GB with 2 8GB aftermarket parts?) and grab the faster 750GB 7200 rpm drive with the higher resolution screen. Option 3: Grab a refurb October 2011 MBP 15 with similar specs. Option 4: Gran a refurb October 2011 MBP 17 with similar specs (yes, I know, discontinued model, etc. Not looking for a rehash of the viability, weight difference, etc.) This would be a machine I use at home. I don't watch a lot of video on my MBP but the larger screen is good since I am older and diabetic, which means sometimes it isn't easy to read. I am not a gamer at all. I'll repurpose my older MBP to bring to work (I work as a consultant and carry a personal system with me.) Also, I am not concerned about resale. I have never sold any of my computers, which means I have way too many (don't ask- I'll simply say a friend used to refer to my living room as "the data center.") No matter which of these I look at, they all come up short in one way or another such that they really all balance out. They're also pretty much the same price when configured, so any thoughts are welcome. Like I said, I'm looking for positive reasons to buy a device, not a situation of eliminating by negatives overall. Thanks, gang.
