I love mine for travelling.

Mostly, I'm just doing email/chat/browsing/writing on my netbook so it is perfect. Battery life is incredible and I've not needed anything on my netbook that I couldn't download.

That said, I don't think it is a replacement for my MacBookPro - just a great addition.

I'm headed south next week for a vacay with friends, and I'll have my netbook with me so I can keep on top of work, but I won't be doing any "heavy lifting"... literally and metaphorically.

My computer collection is now "Small, Smaller, Smallest" with my Macbook, Asus netbook and iPhone.
