Microsoft's series of Surface Pro devices are our PC of the decade. Released during what many called the "post-PC era" of declining laptop sales, Microsoft kept pushing the concept until it finally resonated with audiences around 2015. It can also be credited with reinvigorating a stagnant industry keeping laptops not only relevant and exciting but keeping sales alive too. Initially mocked, the Surface Pro has become the poster child for innovation and a dramatic rethinking of what a laptop could be for modern users. As we head into 2020, the design is so iconic that companies like Apple and Google are borrowing heavily from the model. The Surface Pro is now accepted as a legitimate alternative to the traditional laptop. It also solidified Microsoft's hardware ambitions and is the base for all future Surface hardware.

Back in 2012, Microsoft was coming off the successful Windows 7 desktop OS, and it intended to usher in the era of Windows 8 with new standard-setting hardware. Surface RT – and later Surface Pro – were those devices. The original Surface Pro came out on February 9, 2013. Unfortunately, Windows 8 was received terribly, and while reviews for Surface Pro were mixed leaning towards positive the consensus often came back to one question: Who is this for? Horrendous battery life was also an early issue with reviews nailing it down between 3 and 5 hours. Then there were the other complaints like heat, noise, awkward "lapability," and limited to 4GB of RAM with 64GB of storage (only 23GB available) while priced at $899. To the credit of many reviewers, many saw the potential of a Surface Pro, but it would take more hardware iterations to change the tide. Tech media were still harsh on Microsoft's Surface ambitions, especially since Apple's iPad was destroying everything in its way. Apple's CEO Tim Cook famously referenced the Surface experiment suggesting Apple would never follow that route: "You can merge a toaster and a refrigerator, but that's probably not going to be pleasing to anyone."

If you want to pinpoint the moment when the team behind Surface figured out what people wanted, it was June 20th, 2014. That's when Surface Pro 3 went on sale and with it a complete redesign to the Surface Pro we know today. As noted in my original review, the design adjustments from Surface Pro and Surface Pro 2 were substantial: 3:2 orientation (versus 16:9)

12-inch display (versus 10.6-inch)

2160 x 1440 display resolution (versus 1920 x 1080)

Core i3 and Core i7 variants, in addition to Core i5 (only Core i5)

Matte grey (versus black)

N-trig pen (versus Wacom)

'Connected standby' (versus not supported) Many of these are still the core features of the Surface Pro brand, especially that fan-favorite 3:2 aspect ratio. A year later, with the release of the lower-cost Surface 3 in May 2015, Microsoft passed the $1 billion in Surface quarterly revenue for the first time.

Surface Pro 4, which came out in October 2015 refined the Surface Pro 3. With a slightly larger display (now 12.3-inches), Windows Hello facial recognition, and faster PCIe storage, Surface Pro 4 would kick off its now-familiar "modest improvement upgrade cycle" for the Surface Pro series. But perhaps the most significant fix was for the Surface Type Cover, which now had a larger trackpad and spread-out key design. I called it "the most notable change" of the release as it finally addressed one of the most criticized aspects of the Surface Pro: typing. Later, in 2017, Microsoft would achieve another first: a true fanless Core i5 model. Unfortunately, not all was perfect, though. Hot bagging Bumps, bruises, and new challengers

Surface Pro's design with a kickstand and keyboard cover forever transformed laptops and PCs. Companies like Dell, Lenovo, and HP all have "business editions" of similar 2-in-1 designs picking up Microsoft's slack in the enterprise. Even the wacky ASUS ROG Mothership borrows a similar model for an absolutely insane gaming rig. Surface Pro is so iconic it now regularly shows up in cartoons like American Dad, and Pokémon. This point may seem silly, but for cartoons to work, whatever is shown must be easily identifiable. When you see something, you have to know what it is immediately. A design entering pop culture – whether cartoons, TV shows, or movies – is a sign of broader acceptance.

Microsoft still has more work to do with the Surface Pro – there can never be too much battery or processing power – but the overall concept is here to stay. Surface Pro X is an offshoot pushing mobility even further. And the forthcoming dual-screen Surface Neo is an even more radical theory of mobile computing that is about to kick off the next decade. For all its struggles and people calling for its demise, the Surface Pro is proof that good ideas – over time – can become a winner.
