All this worrying about the "underpowered" rMB running future releases. You really think Apple is going to release a new OS and not make sure it runs on their shiny new laptop?

I have a Core 2 Duo 2007 iMac. It runs Yosemite and the latest apps just fine. It's now the slowest machine in the house, but it works just as well as it did before.
 
Yosemite runs on 8 year old hardware. So i'd say you'll get 5 years at least.

"Some" 8 year old hardware.... actually it runs on higher end hardware as my early 2008 Macbook hasn't been able to run anything past Mountain Lion. But as someone had previously mentioned, it was the 32 to 64bit transition.

Yeah the pre unibody macbooks macbooks are a bit of an anomally there.
 
The base model rMB may struggle with future releases - it's not exactly high powered.

Another concern is the USB-C port - it's a single point of failure - and it's going to get a lot of use being both combined power and data. On top of that, there is no MagSafe connector, and in the real world, people trip up on and yank their power cords. They do. That's why MagSafe was invented. How tough the USB-C port will be , time will tell.

I got my macbook last week, so we can expect to use the connector way more during the first days...

And finally not more that on my Ipad. So yes, my ipad/iphone has a single port with single point of failure but:
1/ Never broke any port on my laptops... EVER
2/ We will use less and less ports as soon as you use wifi and you can get a real working day autonomy (I'm plugging it when at home like I'm doing with the phone

For future releases, I think the future (look windows 10 and snow yosemite announcement, optimisation are part of the deal). Maybe in 2 years... will see!
 
Could it be smoother? Yes, the GPU is on the older side of things but as far as running daily applications like Chrome, Safari, iTunes, Aperture, Mail, Office, and even some iMovie it works just fine! This computer is coming up on 8 years old come August and it's still meeting my parents needs just fine.
I'm surprised that one is still supported. Several Macs from 2006-2007 didn't make the cut due to OpenGL support, 32 bit efi, etc. Yours is probably held back by ram more than gpu. Even with an ssd frequent swaps are noticeable.
