Yeah it's a really good setup. What kind of monitor are you using? I have a Dell right now. It's OK. Not bad, nothing great. Am waiting for Apple to update their external monitor.
I have a 24 inch monitor, ASUS. It's OK, but I need more screen. Assuming Apple ships a new MBP this summer I will get a new 13" system and hook it up to my other 24 inch monitor or get a Ultrawide, 34 inch. I do development and need a lot of screen real estate.
