Now superseded, but the Surface Pro 4 is better value than the model it was replaced by – but it won't be available for much longer

Microsoft Surface Pro 4 is a full-blown PC that is actually thinner, lighter and sexier ultrabook

The Surface offers a clear edge when it comes to accessories; I like the fact that the slim keyboard offers a trackpad too, as I can't resist the temptation of using one with a large screen despite the touch screen.

There is a great deal to like and rave about the Surface Pro 4. The design is thinner and lighter for starters. The screen is awesome, there's plenty of power available, the new Surface Pen is better and the Type Cover is a vast improvement on the last one. However, the design is inherently awkward at times, it's more expensive that a lot of laptops and the Type Cover, which you'll pretty much need, isn't included lowering the value.

With each successive Surface, Microsoft has won over new users to its innovative device. Naysayers who questioned the usability of the odd 3:2 aspect ratio screen now accept that for anything but watching wide-screen media, it's actually a likeably useful format, with its gains in screen height very...

While the Microsoft Surface Pro 4 is the perfected version of the Surface Pro 3, there's still work to do for it to truly replace a laptop. The device is the best tablet in the market today, but the fact that it costs Rs. 89,990 without the TypeCover keyboard make it very tough to recommend.

PixelSense display is amongst the best in the market; Powerful; Surface Pen is almost perfect; Fast and zippy performance

TypeCover keyboard not included in cost; Battery lasts for only 4 hours or less; Expensive

The Surface Pro 4 delivers in every single category you could possibly want with a hybrid ultrabook laptop. It's small, weighs hardly anything, and is very easy to use in both laptop and tablet mode. The superior speed and screen quality makes it an even better buy.

The Microsoft Surface Pro 4 is evidence that after a few "hits-and-misses" a company can finally up its game and the result is a refined, versatile system that can pull through any day-to-day task thrown its way with enough power

The Surface Pro 4 is the best Surface Pro yet, but it still makes small concessions as a laptop and tablet.

Editors' note (June 29, 2017): Microsoft has unveiled its followup to the acclaimed Surface Pro 4. Called, simply the Surface Pro, the new version is very similar to its predecessor, reviewed below. The modest improvements include incrementally better battery life, a newer processor and a quieter, fanless design. On the downside, the Surface Pen stylus that came bundled with previous editions is no longer included by default and the new keyboard covers are more expensive than ever. That noted, the new $799 Surface Pro ($1,027 with the Surface Pen and basic black keyboard cover) remains the gold standard for Windows hybrid PCs though it does not warrant the upgrade from current Surface Pro 4 owners.

A host of small refinements cements the Surface Pro 4's position as the best-in-class Windows tablet -- so long as you're prepared to pay extra for the required keyboard cover accessory.

The Surface Pro 4 fits a larger screen with a higher resolution into a slightly slimmer body than last year's model; The pen and keyboard cover are also improved, and this is one of the first mobile systems shipping with Intel's latest processors.

Microsoft still refuses to include the Type Cover keyboard by default, forcing a separate purchase; Battery life still isn't enough for a full day.

The Surface Pro 4 builds on the best parts of the Surface Pro 3, and it finally delivers a solid typing experience with the revamped Type Cover (which is unfortunately sold separately).

Works well as both a tablet and a laptop; New Type Cover and Surface Pen are massive improvements; Still pretty thin and light for the equivalent of an ultraportable

Mediocre battery life; Type Cover is an additional $130
