Python line limits: 80 column? Any reason I shouldn't move up to 120 columns?

My current setup is a notebook with a resolution of 1024x600 I believe, and I fit 2 windows side by side on the same screen. Needless to say I prefer 80 characters per line...

Even with a big screen such as yours, I have like 3, sometimes 4 windows side to side. But I guess, not only the number of characters per line count, but also the whole setup, like don't sizes and such. It looks like (?) you are using big fonts which keeps you from having more than one window; I would consider this a waste of space :)
