My dear friend, that's the definition of compromise. Lighter/smaller vs. being very powerful. I carry my 15" MacBook Pro + iPad 2 in my bag and the next time would definitely go with the lighter product.
I'm not saying I like it. I would probably buy a Retina MacBook Pro if it wasn't "crippled" (for me), now I just use my 2009 MacBook Pro a year longer, hoping for a better rMBP next year. It's crippled for me, but the retina MacBook Pro does more things than anything 95% of the world could hope to do in 3 years (it's a beast).
