Need new Sony computer

I have a Sony Vaio but it is fully loaded with programs and I need to buy a new computer. I love Sony because of its great technical support. They take over my computer and solve everything.

I want to be able to have my new computer transmit wirelessly to my television set so I can watch computer picture and sound on my television set.

I have been using a long HDMI cable but I want to have it work wirelessly with the latest Intel technology.

I have Roku but I don't like it very much. It doesn't show all the content of my computer. I might run across something on my computer, like ESPN, that isn't already set up on my Roku and I would like to be able to watch it wirelessly on my Television set without having to set it up with a code from Roku and all that bothersome stuff.

Netgear has a thing called Push2TV but the computer has to have exactly the right equipment in order to get the signal wirelessly to the tv set.

Also, I did have the HP thing sends the computer content wirelessly to the television set, but I gave the HP thing to a friend.

What kind of Sony can I buy that will be perfect?

Thanks in advance for any help you might provide.
