I currently have 42 tabs open in Chrome (in two separate windows). Yes, it's like a todo list. It would work better if I had a mechanism to de-duplicate tabs that were open to the same URL - sometimes I find that I've got three tabs open all monitoring the same CI build. But I also keep several JIRA bugs open in tabs so I don't forget them, two Gmail accounts and twitter, I've got five-ish articles that I was in the middle of reading, some reference documents for a few projects I'm in the middle of, a couple of youtube videos that I haven't found time to watch yet...
