I do like the rMBP, but I know I could use the 4 cores when I'm at home or just going to work, which is why I wish I had gotten the 15". However, -1 lbs + smaller form factor + better battery is pretty significant when you're traveling abroad with a backpack for a week or two. I'll take less weight + more socks any day of the week. Also, I almost killed myself trying to get power from an outlet at Phnom Penh International Airport. So, personally, I find the 13" a compromise I could have just spent my way out of.
