The Surface Pro 3 is Microsoft's attempt at creating a two-in-one device, which can serve both as a laptop and a tablet equally efficiently. As far as how successful it is – Redmond did say that it is outselling its predecessors – the original Surface Pro and Pro 2 – though, we do not know exact numbers yet. From the looks of it, however, it seems that the adoption rate is slow, with the main concerns being that the device's keyboard needs to be purchased seperately (and it is already an expensive tablet to start with), and that it does not seem comfortable to work with in one's lap, even though Microsoft claims that it is just as comfortable as a conventional laptop; the company even came up with a word when addressing this issue – "lapability".
So, whether CNN management knew about its journalists secretly using their iPads is unknown, but one thing is for sure – it was a low blow for Microsoft. Sure, non-techies maybe didn't notice, but the tech-savvy community is having a laugh.
