I don't know anything about the Wally or the 211. However, based on what Jim5506 says, I'd agree that if it ain't broke, keep the 211.
We recently moved my father into an assisted living facility. He just turned 89 and has an Xfinity DVR after years of being with Verizon. He's in Pennsylvania, I'm in Hawaii.
Coversations go something like:
Dad, just calling to remind you the Ranger game is on now and it's on 3086 for you.
(him) 3086? (me) yes (him) let me punch that in - 3086. It's a lady selling pastry.
(me) I think you typed in a different number. It's 3086. (him) 1-0-8-6 (me) no - 3086
(him) 3-0-8-6. NYR-CI (me) That's it! NY Rangers Center Ice. That's the package you have. Now press enter.
(him) the middle button? (me) I'm not sure. I've never seen that remote. (him) It's a lady selling pastry.
You get the idea.
