A few questions about my XOOM mz604

[Baconbuttyman]

I have had this XOOM for a couple of months now, while it does most of what I like, it doesn't run some apps, the start to load then the cut out and it goes back to the desktop,
It is on 4.0.4, I know Motorola are not updating this unit any more, so what options are available, I do not know any thing about tablets apart from take two and come see me in the morning lol.
I am willing to learn so please speak in layman's terms
