Wow, the Sony device looks very cool on the surface. I found
another one that is similar or claims to be so. I did have an HTPC years ago as I mentioned - wireless keyboard and mouse. It was always easier to walk a few steps to the office to get behind a proper computer when I needed to get on the web. The 25" screen on my desk is fine when you're sitting 3 feet away. I do have a backup I5 system that is doing nothing at the moment but I've been through that. Like Irv, I don't need web surfing at the home theater. I would buy that sort of thing just for coolness. If it doesn't stream as reliably as the Roku, then it isn't for me.
I know nothing of the other device.
All I know is that contrary to Irvrobinson's justified suspicions about Sony, that device I linked you to does stream perfectly. I have now watched whole Opera's on Met Player without a hiccup.
The remote is the real deal. One way up it is a remote, the other way up it is a excellent keyboard. There is a built in gravity switch that always disables the underside and activates the top side, so you never get conflict on the two sides.
Of course you need to open a browser on your TV. There a tons of sites out there you can not stream from ROKU box. With a ROKU you can only stream what they want you to. There are tons of interesting sites you can stream from a browser you can't stream from ROKU like devices. I would NEVER buy a box were the manufacturer determined what I could stream. A device like that is close to useless to me.
Now I can stream from anywhere. My son did several hours of programming for me today and loaded a program that opens up a VPN tunnel instantly so I can now stream from sites that lock out US IP addresses.
Now I am set to watch the BBC Prom season that starts next month. So I can watch opening and closing night as well as every Thursday, Friday and Sunday TV broadcasts, live or for a week on iPlayer.
I can hear the other four days of broadcasts on the radio iPlayer live or archived for a week.
You can get BBC radio on iPlayer in the US, but quality is limited to 180 kbs AAC3. From the UK I can stream 320 kbs AAC3, which is DVD quality and better than the best analog FM broadcast. I have been using this set up this evening and I'm over the moon with it. The best Father's day present I have ever had.
I tried the available commercial solutions and they were hopeless. This DIY program is the real deal.
Bottom line do not limit yourself to a lousy device like ROKU, that is for the plebs.
