not really much difference, i have never used more then 40% of my RAM. The reason i got it was because it wasn't that expensive and also i wanted to future proof my laptop a little. It is Crucial Ram.
I agree. There's little difference in price between 8 and 16 in aftermarket ram so there's no sense to buy 8 if you're replacing your ram. Crucial is good ram but brand isn't as important as it use to be. Just get the cheapest ram at NewEgg that has good reviews.
As for the difference in the retina I went with the 8gb. If I had ordered it from Apple I would have gotten the 16 but I had 2 discounts and reward zone money to use at Best Buy which got me out the door at $1860 plus another $40 in reward money. That was just too large a difference in price for just 8gb of ram which wouldn't be used very often.
If i was you i would stay with your 2011 and purchase the new iPad. The reason for this is because other then the retina and the thinner size (which i have seen so many issues with the new rMBP) the specs aren't that much better.
The specs are a larger jump between models then we usually see. The retina is more responsive then any MBP that Apple has put out to date, even the ones equipped with an SSD. What issues? Sure it's not perfect but your dead wrong about "so many issues". Have you used one? Many of the "issues" that I've read about come from problems associated with migration.
A fresh install and manual migration resulted in the smoothest running and most responsive Apple product that I've EVER had! Plus the manual migration trimmed my disk space usage by about 20gb.
Also i have the High Res screen so i don't notice that much of a difference between the two screens.
I went to the Apple store and looked at them side by side. There is a very significant difference between the the screens in clarity, color and especially contrast. So much that I knew I wouldn't be satisfied with any of the other screens. Believe me, I wanted to buy a different MBP but after seeing the difference, well lets just say I sold my iPad 3 in order to help pay for my retina.
like you i thought about selling mine and getting the new rMBP but with all the problems it has i figured ill save the money and buy they new iPhone when it comes out this fall instead.
So you haven't had a retina in your possession, used it for any period of time, or placed it next to your MBP ??? Well that just nullifies many of the statements that you've made.
in the end its your choice.
It is but he's trying to make the most informed choice he can since it's a lot of money for a "laptop".
There are advantages to both the MBP and the retina.
There is very little difference in price between the 2 once you add an SSD and ram to the MBP at aftermarket prices.
There's very little difference in raw processing power between the 2, if any.
There is a difference in responsiveness.
There is a huge difference in the displays.
I went with the retina because the display is what I look at whenever I use my laptop. Of coarse the programs I use play nice with the display. I almost returned it because my 2 most used programs looked terrible on it. One got fixed that very next day through an update and I found a free replacement for the other program.
