It's coming to Laptops, Phones, TVs, Blu-ray players, Pads, Vita, PSTV, PS3 and PS4.

All stated in articles. All stated by Sony. Google it.

I think people are still labouring under the illusion of PSNow being the answer to BC. It's a service designed to offer PS games to the widest possible audience. It could even be PS5. There is absolutely no reason why games couldn't be streamed that go well beyond the capabilities of the PS4.

PC gamers arent going to pay more than $5 for old PS3 games. Onlive was a failure on PC even with a subscription service. Most PC gamers are aware of what is going on in the console gaming world. It certainly can work but I really dont think Sony is missing out on that much of the gaming community as it stands.

I believe they should actually allow people to buy games... And have this for PS1/2/3, Vita and PSP games.
People (including myself) would pay for that service and I would buy a digital library played across multiple devices (including PC, PS4 and why not competitor consoles :)).

PS Now will be a failure like Onlive.

Seeing as to how it's just going to be PS3 and backwards games, streaming PS3 games to master PC Race rigs would be laughed at as not worthy for the 4k overlords.

Dull fanboyishism aside, those who love games for the sake of loving games but play on pc would love to play certain console game exclusives

I'm very doubtful of this idea. The PC master race and other PC gamers would strongly refute this app just because it plays sub 4K PS games. They would want upscaling and the application cannot make it possible. And there's also the issue that not every game can be available due to copyright. Usage would falter due to Steam being a more wildly popular application unlike Uplay and Origin, that despite being necessary to play Ubisoft and EA games respectively, are panned by the gamers. I believe they should skip PC and concentrate on the other devices, and maintaining the PS4 momentum.

And another one who has no idea how PSNow works. Why would you need a powerful PC to run PSNow when it is easily able to run on 10 year old PCs.

Your whole argument doesn't work. PC players are PC players because they have higher standards. Streaming games is pretty much the lowest quality you can have. Way lower than actual consoles. You will have to deal with massive input lag, downgraded visuals and compression artifacts. No PC player would want this.

If anywhere, Sony should put PSNow on Smart TVs. That's where it belongs. That's where people can play without owning the hardware.

It sounds like you haven't actually tried the service.  I played Dynasty Warriors (cant remember which exact one) on the service, via my PS4, and found it to be INDISTINGUSHABLE from playing on my PS3 "natively".  No discernable input lag, no pixelization of the graphics.  I am running a 35mbps down/15mbps up Frontier Fios connection, connected via Wifi to my PS4 (effective speed, as tested via the settings on the PS4 is 16 down/3 up).

I would not hesitate to use PS Now on a regular basis if and when they fix the pricing!

Are you own a powerful gaming rig that you regularly play on? Do giant 720p pixels hurt your eyes? Do you think 30fps are almost unplayable?

If you answer any of these questions with "no" then  you're probably not in a position to judge what PC gamers would consider bad.

30fps have a bad enough input lag inherently. You can't tell me it doesn't get worse when you send it through the internet and WiFi no less.
