This is a serious question, not an attempt to be rude or start an argument. I came to look at R# as I had heard good reports about it, and wanted to see if it was worth buying.
I've spent a fair amount of time looking through the features, and the vast majority of them seem to duplicate things that are already in VS2010. If so, what's the point of spending money on an external tool, that provides the same functionality, and requires me to learn a whole new set of keyboard shortcuts (which annoyingly conflict with ones already in use).
I'm sure I must have missed something, but even after spending quite a long time reading the features list in detail, I didn't see very much that seemed to justify the reputation.
Please enlighten me. If it really is a good tool, I want to know. If it's not, I also want to know!
