I'm thinking about purchasing a Roku streaming media player. Does anyone have any pros and cons about the product.

Hardly any cons, is just plain awesome. What type of Roku streaming player are you buying?

Can you use Ruko in the UK or is it just for amercia ?

i don't see why you can not use on in the UK. the only thing i know about them is that you would need a wireless router and that's pretty much it and you are able to watch your favorite shows without having to subscribe to any cable/satellie company.

Roku 2 XS is a good choice.
