I've installed Windows 8 on two different tablet PCs so far: an HP Slate 500 and an HP EliteBook 2760p convertible tablet PC. Both are capable of touch input and both support an active stylus pen. The HP Slate 500 doesn't have the screen resolution to support the new Windows 8 "apps" but the 2760p does (but it doesn't support snap).
Overall, the apps look/feel and function very much like other tablet apps you'll find on the iPad or Android tablets. They are elegant, easy-to-navigate, and function quite well. I've played around with your standard apps like Amazon Kindle, Skype, TED, Netflix, Skydrive, Dropbox, and others. I also really like the new touch on-screen keyboard that's built into Windows 8. It's much better than they on-screen keyboards we saw with Windows XP Tablet, Vista, or 7.
Apps designed and built for Windows 8 or Windows RT are leveraging a screen resolution of at least 1024x768 but if you want to multitask using the new snap feature, you'll need a PC that has a minimum screen resolution of 1366x768.
If you're not using a touch-screen device, you'll want to memorize the following keyboard shortcuts:
- Windows Key: Switches between the Start screen and the last application used.
- Windows-C: Charms bar.
- Windows-D: Desktop.
- Windows-E: Opens the computer/file explorer.
- Windows-I: Settings.
- Windows-R: Run dialog box.
- Windows-X: Simple Start menu.
