I have a 2 and my friend has a 3. I've been looking at getting a 3 from the refurbished online store so I don't have to upgrade the connector. After playing around with the 3, it's not faster at all but it does look better. If I was on it all day I would upgrade but for the half hour or so I use it before bed, it's not really worth it. I'd say comes down to money. If money is no concern get the 3. If you're being sensible with your purchases, then the 2 is more than enough.
