Well, my experience with tablets (or handhelds) is not so good with Roon. Tested iPhones and iPads.
That together with the thought of a device that don’t scream portable made me find that.
You say it’s slow. Roon will be it only task. So you say it will work but do it slow?
You can probably load Roon but you might have trouble running it. The resolution looks a bit light and Roon also needs a bit of graphics horsepower since it using OpenGL to process the graphics.
And sorry for not being explicit, but when I mentioned tablets I only meant Android tablets. I forget there are people who use other things. I have been using a Samsung Galaxy Tab S2 for over a year and a half. Butter smooth, no hiccups and I can listen from the tablet itself.
I haven’t seen anyone use the Odys Winbox, so it may be unlikely that anyone can tell you that it works for them. The things that would concern me are the low cache on the Atom processor and whether the graphics can support OpenGL 3.0.
If you have access to a demonstration model or can trial one of the devices then I would definitely reccomend loading Roon onto it and seeing how it performs before finally purchasing.
There can be a false economy in buying an under spec device “cheaply”, finding that the user experience is unacceptable and then purchasing a within spec device later anyway.
