I ran across the Consolas font from Microsoft today. I love it. I'd been using Courier New in 9pt and have now switched to Consolas 10pt. Much easier on the eyes. But not at first. It displayed quite poorly until I enabled ClearType in my display settings.
I've been using LCD monitors for a long time and why I've not switched to ClearType, I'll never know. It's like my glasses suddenly became more effective.
How many other cool things have I missed? One can never really know.
