Well, I don't need most variety of music, known to man in the history of man. My music taste doesn't seem to change anymore.

I already have all my favorite songs of the 1980s, 1990s and 2000s on my phone, it only uses a fraction of my microSD card.
No further streaming costs or dependence to have an internet connection... and of course the music app doesn't stop playing when the display is off.

Man, I'm feeling old while writing this.

I'm not interested by cloud gaming, I think it's too soon, the technology is not ready, too much lag and other issues. Also it's not as cheap as it seems. First there's 120 dollars for the controller, that's too much for a system that boasts of saving you the trouble of getting hardware. Then there's the subscription, I'm not too hot on subscriptions as I like to control how much I pay for stuff. And the worst part is that despite paying for an overpriced controller AND a subscription you still have to pay for games... FULL PRICE mind you!

And as if all that wasn't bad enough, you are paying full price for games you ONLY "rent" or get an access to as you don't own them. It's just a pass to play those games. Why should I pay full price for just a pass that Google may decide without notice to take away from me at any time?

Also I don't play on phones, I use my TV for that.

I have played the Stadia for 10 hours or so, and found that is actually really good. I cannot even tell that the game is being streamed. I have tested it on internet of about 40mbs and it still ran perfectly. I have found that it almost never lags and feels responsive.
The UI is really bad, but the actual playing of games is solid.
