I had a 13 inch white macbook for 4 and a half years. (I still have it, but that's what I primarily used).
I just bought a 15 inch Macbook Pro and the size is perfect, IMO. I have to admit I was a bit worried it would be too big but it's actually the perfect size. It even fits in my 13 macbook's carrying case and is lighter than my white Macbook. (Though that is old now.)
I don't know you, but I would find it tough to be disappointed and believe that you chose the wrong one with the 15 inch. It's very portable.
Also keep in mind I believe the 13 inch's speakers are not as good..... (Pretty sure that's right).
