Opera Mini
You can configure Opera Mini to render your website on Operas servers and send a static (super small) version to your mobile phones browser. This is really good when you have a slow connection and pay for the amount of data. According to Opera: Mobile internet users in Africa have already saved $500,000,000 over the last 10 months, while using the Opera Mini mobile browser and there are also a large user base in India.
The mobile web has room for improvement to work better and look better in Opera Mini. These are listed as blocking tasks.

Why are remote browsers important?
The idea with the remote browsers is to make pages small, fast and cheap for people with slow internet connections.
It's hard to get numbers how many users that actually use the mini version (=remote) but for example Opera is the most popular browser in most countries in Africa and UC is biggest browser in India.
What's the problem?
Today Wikipedia doesn't work so good on remote browsers (see the subtasks). That something we should fix to be able to bring free educational content to the world.
