I purchased a new Slingbox HD from Amazon and just hooked it up. I then purchased the Slingbox App from the Marketplace and it works really well on my EVO using both wi-fi, 3G and 4g. Next I enabled my EVO's hotspot feature, connected my Acer Aspire One Netbook to my EVO, and connected to my slingbox through a web page interface using Firefox. Although it takes a moment to "ratchet down" the stream, it is VERY watchable and slightly better than Sprint TV in 3G mode. In 4G mode it is noticeably better. I really hope they roll out 4G to the rest of the country in a timely fashion, but it is very watchable on 3G. I highly recommend it for anyone wanting to watch their TV on the road. I have been a "slingbox holdout" for a long time. The EVO convinced me to pull the trigger. My slingbox HD is hooked up to both my HD Directv box, my SD Directv box (I record different shows on each) and a composite video signal from my home security system. All work flawlessly! If you have been on the fence about slingbox (like I was) and you have the EVO....I say DO IT!
