Its not worth buying at all far from it does not even include native Bluray/DVD playback any longer to save on licensing fees for MS you have to buy a 3rd part codec
No version of windows has ever included that. VLC ftw \o/
2: MS App store is obviously DRM heavy as the entire Windows 8 OS uses your Gamertag as its logon account now. MS are trying to build a Steam like store here to corner the market.
Yup they really want something as successful as Apple's app store, not to mention Steam. You can create a local-only user account at the expense of the social integration (boo hoo), they just don't advertise it.
I think it will fail miserably for hardcore gamers they will have no interest whatsoever but the casual gaming market is massive so perhaps it will find some audience as Windows 7 is being discontinued on 25th October (stock up now!!).
It's fast, I'll give it that. Maybe faster than 7. I have the consumer preview installed on an old-ish touchscreen laptop (AMD dual-core CPU @ 2GHz, 2GB RAM) and it boots in about 40 seconds and runs smoothly. The big turn-off is Metro which is just a terrible UI even using the touchscreen. There are simply no visual cues for regularly-used functions. On the desktop, the start button only appears when you move the pointer to the bottom-left corner of the screen.
Example: To shut down a Windows 8 PC (from Metro)
- Click your username at the top-right corner of the screen.
- Click "sign out", wait for it to sign you out and display the welcome screen.
- The welcome screen itself is a background picture, the time & date, a wifi icon and a power status icon. No buttons or controls. Left-click to get the actual login screen.
- Click the power icon (no text label) at the bottom-right corner.
- Click Shut Down.
To shut down a Windows 8 PC (from the desktop):
- Move the pointer to the bottom-right corner of the screen. A secret menu appears.
- Click the Settings icon. Make sure not to move the pointer away from the menu or it will vanish.
- Click the power icon.
- Click Shut Down.
To shut down a Windows 7 PC:
- Click the START button.
- Click "shut down".
I'm not looking forward to supporting end-users with Windows 8 PCs

It's a classic example of moving backwards for the sake of being different. To be fair it's not finished yet and these things could improve, but MS had better get their finger out. The biggest worry is that MS want to focus on Metro as their primary UI going forward - it simply isn't appropriate for a desktop PC. On top of that they want to move to a lock-in business model similar to Apple's app store, and that is not good for the consumer. It's also a big "up yours" to the open PC platform that allowed them to rise to success in the first place!
MS are so keen to make this work its only £14.99 to upgrade a vendor OS if your buying a new device with it.
They had similar upgrade pricing on vista and 7 too as part of the "express upgrade" scheme, the price varied by OEM. Some were free, some wanted up to £30. I got so many calls from people complaining that the "free" upgrade wasn't free
To be clear: The "express upgrade" scheme applies to new Windows PCs purchased within a certain timeframe before/after a new Windows release, intended to avoid a potential slump in PC sales leading up to the release date. Buying Windows 8 by itself will be £50+ easily.
Answer to OP's question in a nutshell: It might be faster than win7. But at what cost...
