I'd love to go wireless, but with two stories plus a separate steel shop set on concrete, it's not worth the hassle ... unless Dr. Mercola is right about EMF ruining our health.
And maybe I missed something in our Hopper replacement discussion, but the Dish guy who installed my system suggested today an even simpler Hopper swap approach: Cable my old Hopper directly to a new Hopper, tell the old empty one to regurgitate its contents into the new one, and when that's complete return the old one to Dish. No middleman -- no EHD, no hub, no added risk of losing some content during two transfers -- and I can watch TV as usual during the day or two it takes to transfer the contents.
BUT THAT, you accurately observe, leaves me without extra storage capacity.
To which I say, If I need more shows stored than one Hopper, let alone 2 of them, can handle, I need to get a life. It's sorta like the endless hours, days, and weeks some of my buds spend watching sports on TV; I don't watch sports ... I DO sports. When we were preparing to move away from a neighborhood decades ago, the neighbors admitted to betting on which toys I would use each weekend. They pretty much stopped doing that after one 3-day weekend in which I went skiing, windsurfing, serious desert dirt bike riding, 4-wheeling, and snowmobiling ... not to mention using one or more of them on most weekday evenings. Holy COW but I loved Utah!
