Can Microsoft Surface Pro 3 replace the laptop?

Many people have both laptop computers and tablets and use them for different tasks. Microsoft on Tuesday redoubled its vision that the two devices should be one and the same, introducing a new version of its Surface tablet with a larger screen.

The company's new product, the Surface Pro 3, has a 12-inch screen, larger than many small laptop screens. The more spacious screen reflects a sharpening of Microsoft's belief that it can still distinguish itself in the tablet market, where it is currently an also-ran, with a device that meets professional and personal needs.
Microsoft argues that current tablets, most notably the iPad, are great for watching movies and other forms of entertainment or reading, but are far weaker when it comes to getting work done. The company's proposition is that the Surface can do both well. A bigger display, Microsoft argues, will let people look at more than one application on their screens at the same time — like email and a word processor— as they can on their laptops.
