In my experience, the onboarding experience sucked and it crashed every time I used it until I installed it.
"Very cool!! Tons of features. Very fluid. Definitely a step in the right direction by Yahoo!"
Sounds like someone from PR wrote that.
And 500 is a tiny fraction of the total number of people at Yahoo.
All that put together would add up to a lot of votes, wouldn't it?
Ever considered others might have had a different experience? I took it for a spin (iPad2) and it seems pretty nice actually - and yes, it did not crash. I don't see it as a replacement for Safari, but it looks perfect for leisure browsing.
