You can't beat the price of a base 13" MBP with aftermarket upgrades to RAM and SSD (later on, as needed).
That's basically what I've been doing for the last 3 MacBooks I've bought.
The upgrade ability is just awesome!
I second that!

I bought mine May last year (right before the 2012 models came out, but I was afraid they're gonna pull it out in favor of Retinas and didn't want to risk that

I've swapped the HDD, added RAM and I love it! Well a couple of months later I found a great deal on 15" cMBP (with 2 SSDs, 1GB VRAM, high res) - 1 year old, but in perfect condition and... I couldn't resist

I know I could probably do just fine with the 15" alone, but I like to have separate home and out of home computers. That's just the way my old fashioned brain works

Before my turn to Mac I had a stationery PC + a netbook (man, that was a horrible idea, when I think about it now. That tiny 10" screen and cramped keyboard

Anyways the 15" is my main machine (with SSD and the 750GB HDD I took out of the 13"), hooked up to a TBD and the 13" is my "the on the go" laptop. And it handles pretty much everything I need it to handle - InDesign and Photoshop are the most "extreme" tasks I throw at it, but that's what I need it for. To start something, to try out or develop some ideas, that I then finish on the 15". And it just works. And with the SSD and 8GB RAM I can't find a usage that would make him stutter, so it suits me just fine.
Of course it's not the best gaming machine, so that's a job for the 15" to handle my very occasional gaming (Colin MacRae, F1, Shank etc
