Have you joined the tablet revolution yet? If not, now is as good a time as any with new offerings from every major player in the market. There are brand new releases covering each format; iOS, Windows 8, Android 4.3, and Kindle's new Fire OS.
But which one to choose? There's an article over at engadget that lists them side by side. It's aimed at consumers rather than professionals, and consequently favours Apple. You'll have to make your own mind up if you intend to use it for business.
