Windows 8 is "a huge leap forward" for Microsoft, but it'll take users a while to adjust, thinks Charles Arthur, the Guardian's technology editor.
James Harvey, Commercial Director of technology manufacturer Asus, said a Windows 8 success story would be good news for his company.
He said Asus is making "a whole plethora of new devices" using the new operating system in the short-term and "in the next few years you're going to see some very interesting devices coming forward."
- Microsoft is desperate for the new-look, touch-friendly Windows 8 to bring itself up to date with customer demand
- Early reviews of the Surface have been mixed, generally praising the slick hardware, but faulting battery life and the limited software and apps available
- Some say the first Surface model is not compatible with old Windows programs
- But, the three models for sale on Microsoft's US website are already on back order, suggesting strong demand
- There are expected to be 5,000 third-party apps available in comparison with the iPad's 275,000
- Some big names such as Facebook will be missing
When Microsoft's Surface was first unveiled in June all didn't quite go to plan. As company executive Steven Sinofsky opened up Internet Explorer the tablet crashed.
Here's how the Surface and iPad compare:
- The Surface boasts a thickness of 9.3 millimeters, versus the iPad's 9.4 millimeters
- It weighs about 1.5 pounds. Apple's iPads weigh 1.44 pounds and 1.46 pounds for the WiFi and 4G LTE versions, respectively
- A 10.6-inch-diagonal screen, compared with the iPad's 9.7-inch screen. The Surface also features a unique 16:9 aspect ratio
- The Surface has 32 GB or 64 GB of storage. Apple's iPad has 16 GB, 32 GB and 64 GB options
- Surface has a built-in stand and comes with a cover that doubles as a keyboard
It comes as no surprise that Microsoft is looking to take a chunk out of the tablet market.
Even though over 1.5 billion computers and devices are currently using a version of Windows, the firm is more concerned about its prospects for growth.
Sales of tablets are expected to triple in the next two years, topping 180 million-a-year in 2013, easily beating traditional PCs.
The sudden demand for tablets made a big dent in Microsoft's income. Two years ago Apple overtook their revenues for the first time.
The share Windows has of the PC market is around 75%, down from 96% three years ago.
But some analysts say that share falls to around a third if you add the PC market together with the smartphone market.
Microsoft officially launches its new operating system Windows 8 today alongside its first tablet, called Surface. Once the world's biggest technology company, Microsoft is looking to claw back market share lost to Apple, Amazon and Google.
