Vrapper
Great -
I've only used it a little, but vrapper is nice because it makes you not miss the navigation from vim too much. I still switch to Gvim for heavy text manipulation.
Very similar to ViEmu in Visual Studio.
Firefox
Great -
Extensions like Adblock, flashblock, dictionary tooltip, firegestures make Firefox fit into my way of browsing. (And there's always IETab when your company's internal websites don't support modern browsers.)
I love the search bar, search keywords, and a lot of the little niceties that make going back to Internet Explorer unbearable.
