The only review of the Surface Pro 3 that matters – as always, from AnandTech. They conclude:
Surface Pro 3 is easily the best design Microsoft has put forward. If you were intrigued by the previous designs, this is the first one that should really tempt you over. I was a fan of the original Surface Pro, and with Surface Pro 3 I think Microsoft has taken the hardware much closer to perfection. At this point the design needs more help on the software side than hardware, which is saying a lot for the Surface Pro hardware team. Personally I’d still rather carry a good notebook and a lightweight tablet, but if you are looking for a single device this is literally the only thing on the market that’s worth considering. I don’t know how big the professional productivity tablet market is, but it’s a space that Microsoft seems to have almost exclusive reign over with its Surface line. With its latest iteration, Microsoft is serving that market better than ever.
Coincidentally, Microsoft is going for the tackle: you can trade in your MacBook Air and get up to $650 from Microsoft. Any takers? Anyone…?
