DISH Network TV everywhere works on Laptops, Tablets, and Smartphone?s. Just connect the Sling adapter to a 722 or 722k HD DVR and download the app. Being a DISH employee I know you will get all the programming that you are subscribed to and you can watch what you have recorded on you DVR and set up timers for your recordings with DISH Remote Access.
What kind of quality would one get over a dsl connection? My dsl only gets about 650K up. I know it works great over cable internet. I'd hate to spend 100 bucks just to find out my dsl was too slow.
