Before there was the iPad, there was the Tablet PC.
Bill Gates proudly introduced Windows XP Tablet PC Edition (a variant of Windows XP Professional) in 2002, and he operating system got a major update in 2005. Its features were rolled into Windows Vista in 2006, and the entire pen-and-touch input system was refined impressively in Windows 7 in 2009.
And then the iPad came out and made Tablet PCs look like something from a prehistoric time.
What went wrong? If you look closely enough, three problems emerge.
First, the hardware available in the early 2000s simply wasn't good enough to make the tablet experience fun or interesting. Tablets were heavy and hard to hold, and they didn't have enough battery life to get through a working day without being recharged.
Second, these alternative modes of input were considered features rather than the primary mode of interacting with a Tablet PC. Although a few brave OEMs tried to introduce slate designs, the most common tablet configuration was a convertible PC, which functioned as a conventional notebook most of the time and switched into tablet mode as needed. The result was a system that didn't do either task particularly well.
Finally, the biggest problem was a lack of developer support. Even tablet enthusiast had a hard time finding apps that really took advantage of pen and touch input.
And so the entire Windows Tablet PC category was relegated to niche status, selling a microscopic number of units. Within a few months of its release, Apple had sold more iPads than Microsoft had sold Tablet PCs in the preceding eight years.
There's no question that Microsoft learned some painful lessons from the Tablet PC failure. There's also no question that its Tablet PC experience has given it a good head start—at least in technology terms—when it comes to Windows 8. For 2012, its challenge is to prove it can deliver a tablet that people will love. That's a tall order.
