I have my PSR3K now for some time and have been twice on internet to look for new styles, but sofar ... nothing! So I find the internet-button on the PSR3000 not usefull at all. I like to know from other owners if they do anything usefull with the internet button on their keyboard.
Otherwise I find the PSR3K a great instrument.

I must agree...I have never found any use for the "Internet Button".It's mostly used to connect to a Yamaha site where you can download midi etc.
It's easier to use your computer for that,and then you also have a choice.
Otherwise the 3k is fantastic.
