Sprint : Hero Does Better Than EVO / Watching YouTube Videos At Least

So here is the story. I'm at my local Sprint store fondling the new EVO and contemplating when I get an upgrade and maybe I should get one or should I wait or.Anyway, the phone was fully functional and on 3G, so I thought I would check out YouTube. I brought it up and searched out a video I had watched before and cued it up. When it played, and for whatever reason, it had super resolution and looked great, but it would not play more than a few seconds without stopping then starting, stopping and starting again, etc. I thought this was pretty weird, so holding the EVO in my other hand, I pulled out my Hero and cued up the same exact YouTube video. When the vid played on the Hero the video guality and resolution were not as good as the EVO's, but it played perfectly and seamlessly all the way through, no starting and stopping at all.
