One thing to keep in mind is that almost all browsers on Android seem to be tracking their users. For example, I like Dolphin HD the best but I will only use version 7.02 because it apparently doesn't track. The newest version in the market now tracks again.

Personally, I don't like that they know all of the sites that I visit. It's unprofessional and highly intrusive, but I also don't like the extra resources (battery power, bandwidth, processor cycles) used for this spying.
Right now, I'm using Dolphin HD 7.02 but I cannot wait until an alternative comes out. Firefox and Opera Mobile need some refinement but I will be switching to one of those or Chrome some day.
