This is a different take on the 8 Vs 16Gb question. When the iPad 3 came out we all had to re-adjust what was acceptable for a base iPad when everybody bumped up their apps to retina. Which leaves all the current metrics like page out useless. Can we do the same, but for ram. For all those moving from a cMBP tell us how much ram you used to use and what you now use, and what programs you have open to make the change. I'm a 8gb because I don't really want to spend the money on what will be a second machine for internet, photos and work (excel and word not photoshop). (I have a 3.4 iMac with 12GB as a primary) Or wait the reset time. I occasionally play games but as a soon to be new dad I think that will be going out the window. I also want the machine to arrive soon and don't want to go to the back of a 3-4 week queue as I'm currently due for delivery 12-18 Jul.
