So to clarify your mom does do some gaming which is on the wii? What about your dad?
Ya my Mom plays the Wii. My dad doesn't play the Wii, but he does play poker games on PC. If I give them my 360 I was planning on getting him one of those poker games on XBLA.
Even I have some trouble figuring out the 360 UI, so I'm not so sure that would be a good choice.
The WiiU has a pretty accessible interface, especially with the gamepad, but the range on it probably won't go throughout the house. Since they have a Wii, the ability to use a Wii remote would also probably be useful for them. The touchscreen on the gamepad would probably be a lot more handy than a 360 controller for using youtube, facebook, etc.
I'm wondering if either of those are really the best option though? You know your parents better than I would, but are you sure they would want to do those things on the TV instead of getting a tablet or something?
If I give them my 360 I will have them just use kinect voice commands and I will pin all the apps they would use to the pin tab so they never need to navigate past the main menu. When the Wii U launched, I heard that it would freeze and the only way to shut it off was to unplug it. Im not sure if thats still the case but my parents don't have the patience for stuff like that.
I thought about getting them a tablet but I dont think it would give them the same value as a console. My parents wouldn't take the tablet out with them, for fear of losing it, so I feel like having something like the Wii U gamepad would be a better alternative.
If they don't play games, why not a Roku box or a blu ray player with those features?
Why would you give them your Xbox 360? Don't you go back and play old games? Do people generally get rid of their old consoles the second a new one comes out?
They have a blu ray player but it only has apps like netflix and pandora. What they really need is just a second device for internet browsing since they only have one desktop pc which isn't located in the living room with the main tv.
I have 5 different consoles, there are way too many games for me to play to have any desire to go back and play old games I have already beaten. And Im not like most of people on this site, I don't hoard games so I have no backlog. If I buy a game I play it right away and if I like it enough I go for all the achievements and never play it again. Because of this I have played/beaten every game Im interested in on xbox 360 so there really isn't any reason for me to hold on to my 360.
