Well, I've given yourminis.com a decent shot (see my previous post). But I am switching back to Google's personalized start page, mostly due to performance issues.
Yourminis looks way better and has some great features, but it just seems to run a tad on the slow side. Believe me, when you use a page several times a day, just a few milliseconds of delay to find what you want becomes annoying.
I'll keep my eye on them, since they are still very new and could actually optimize their platform for better performance. But until then, I'll stick with the lean, mean, HTML machine.
And to my friend Roy, I agree with your comments. Flash is a great platform and any company basing their product on Flash could be an innovation leader, if they know how to balance power, performance, and usability.
