Nokia has unveiledset to go head-to-head with , which went on sale earlier this week.
It's not entirely clear that what the world needs is another Windows RT tablet, as the response to the operating system.
Microsoft is keen to push Windows RT because the operating system gives the company (in theory at least) a much-needed way to compete on price against the iPad and even cheaper Android tablets, without cannibalising Windows 8 sales too much. However, the confusing branding of Windows RT, the strange desktop-plus-tiles interface and a lack of killer apps has seen Windows RT-powered devices struggling in the market.
Earlier this year Microsoft had toas a result of sitting on millions of unsold devices. Since then is has been running a number of special offers aimed at running down this excess inventory. And while the Surface 2 (and its enterprised focused big brother Surface Pro 2) do address some of the early criticisms of the devices, the tablet will still face an uphill struggle .
And while some of Microsoft's hardware partners initially offered RT devices, now only Microsoft and Nokia (soon to be part of Microsoft) are still left making them.
The smartphone-phablet-tablet environment is changing fast, and Microsoft's strategy is still evolving. So while Microsoft is sticking with Windows RT, longer term, the decisions about which operating system to put on which hardware might get more complicated as Windows Phone and Windows RT begin to converge: we could see
Another complication is that Microsoft is the process of acquiring Nokia's devices and services business, which means that the Lumia 2520 and the Surface 2 will be stablemates.
As Forrester Analyst Thomas Husson noted, "despite a more affordable price, the respective positioning of Nokia's new tablet versus the Surface 2 is not obvious and will have to be dealt with post Nokia's acquisition."
"These new devices will help Microsoft get traction in net new Windows acquisitions, but we're still far removed from a significant installed base of consumers that it will naturally attract mainstream marketers and third parties," he said in a statement, while Gartner analyst Carolina Milanesi said on Twitter that looking at the Lumia 2520 she struggled to see how Microsoft will be able to keep both addressing consumers "unless the Lumia drops in price". One option may be for Lumia to become the consumer brand and , she suggested.
You can see the full specs for both devices below: the Surface has a slightly bigger screen, is slighty heavier; the Lumia 2520 has better connectivity options. The Surface with its kickstand and VaporMG casing is probably the most elegant looking of the two, while the colourful Lumia is being aimed more as a companion device to Nokia's Lumia smartphones.
The big question is whether there is a Windows RT tablet market big enough for both.
