One way or the other I am hoping to see the MBPr updated. They seriously need to double their internal SSD to 256 GB for the low end model and double the RAM to 8 GB. At that point, I'm happy enough paying $1300. Not pleased with paying $1500 for brand-new.
I've been buying Apple products for 10+ years now. And I've noticed that it is very much Apple's MO to have their stock configs slightly less powerful than you'd hope/expect given the price of their products. Whether it's RAM, hard drive capacity, or similar, they will always under power the base config, to squeeze slightly more profit out of the clueless general consumer (who probably has no clue how much RAM is optimal, I've had friends in the past year come to me with Windows laptops with 3GB RAM. 3GB!) and to bump techies to the higher models which allow user configuration.
IMO it is a bit greedy, since they are high end computers and should come with high end specs to match, but it's not enough to switch me off Mac OS X. I'm pretty sure that by the time their stock configs include 256GB SSDs and 8GB of RAM, you'll be needing 512GB and 16BG. If you doubt that, look at the iMacs. The 21" model ships with a 5400RPM HDD!
Sigh, I've been holding onto my iMac late 2009 i7 waiting for the new mini. Guess I can wait until June.
I have to say, a 4.5 year lifespan for a computer is pretty depressing. Why don't these things die more quickly? Then I could get a new one faster.
I have the exact same computer. In 2011 I bought an Intel 320 160GB SSD on Black Friday, and following an iFixit repair document, replaced the DVD drive with it, with no trouble at all. The computer was then 10x as fast, because guaranteed your bottleneck is the HDD. Then I upgraded the RAM to 16GB 1333 MHz, the most it can handle. It's now blazing fast as ever. Easy as fast as my Macbook Air. I have the OS on the SSD and my iTunes, iPhoto and Movie library on the internal HDD, which I did not touch. Or you could combine the two into a fusion drive (instructions on Macworld) if you wanted, but I like to keep manual control of things.
You should do the same. I guarantee if you do that, you will not see much of a performance increase even from a 2014 Mac Mini (since the i7 processor was a great one, and desktop, and the Mac Mini one will be a mobile processor).
