I know this topic is really already past, but what about a fully up to date web browser. Full CSS standards compliance, JIT javascript, nice developer tools, memory models, full garbage collection, just the web browser we all want right. Pay attention because here is the interesting part. Sell it to Microsoft. This is not a web browser where you are trying to capture the market. No just sell it to Microsoft because they aren't going to fix their browser anytime soon. I imagine they can't. It's too old, and maintenance has become a nightmare. That's why their browser is so behind the times. So, they got a problem, a big one, so someone should fix it for them.
