I used my Dreamlink T5 for 3 years and still sold it for $100 a few days ago.As far as future proof there's not much that is as pretty much the time you buy your box within 6 months it's already obsolete something better faster than yours open but I'm not sure I haven't tried it yet you might want to take a look at Google's new streaming device I hear a lot of great things about it but I haven't tried it out personally myself I love and use the Amazon fire cube TV it works great for me
I am looking into the Google device and also heard lots of good things about it. I will be researching that, for sure.
