Windows tablets through the ages: The good, the bad and the ugly, in pictures

Microsoft has been involved with tablets since the early 90s, which must have made it all the more frustrating to see Apple turn up and grab much of the market with the iPad.

Microsoft is trying to claw back ground with its range of Surface devices, so here's a look back at some of Microsoft's earlier efforts in the tablet market over the last decade. For more on the history of Windows tablets, read Surface tension: The long, strange history of the Windows tablet.

Tablet PC prototype, 2000

Above is a prototype tablet PC showcased by Microsoft at Comdex in 2000. Evidently back in the brighter, more optimistic year 2000, orange and white was a perfectly fine colour scheme for a tablet -- if you tried to sell a similarly coloured device now, people would assume it was aimed at the under-tens.

A year later, at Comdex 2001, Bill Gates predicted that the tablet PC would be the biggest selling type of PC within five years. It would take a little longer than that.

Still, flash forward a couple of years and Tablet PC hardware was hitting the market. Here's a convertible Tablet PC from 2002 -- the Toshiba Portégé 3500. It ran Microsoft's Windows XP Tablet PC Edition and cost a mere £1,799.

Pictured above is a 'slate' style Tablet PC from 2002, the Stylistic ST4110, made by Fujitsu Siemens with price tag of just under 2,000 pounds. The handwriting of ZDNet reviews editor Charles McLellan hasn't improved much in the intervening years, either.

This HP Compaq device -- the TC1100 -- was seen by many as one of the more successful Tablet PCs.

While Microsoft and its hardware partners continued to push Tablet PC hardware (such as in this stunt where cartoonists drew caricatures using the device), they failed to gain much traction beyond particular business niches. I wonder what happened to the reporter being drawn?

The Ultra Mobile PC (UMPC) was part of Microsoft's attempt to get consumers excited about tablets back in 2006. This Asus R2H ran Windows XP Tablet PC Edition, and had a passive rather than an active touchscreen. UMPCs struggled to find a market -- too expensive for the consumer, they were rapidly overtaken by netbooks.

Here's one that Microsoft didn't make but probably should have -- the Courier never made it any further than a lavish mock-up, but the unique design had a lot of industry-watchers excited back in 2009.

In early 2010 Apple launched its iPad, which rapidly went on to be the tablet market as far as most consumers were concerned. However, Windows tablets such as this Lenovo ThinkPad X220 Tablet continued to fill gap for enterprise users.

Here's one of the devices that Microsoft CEO Steve Ballmer showcased in his CES 2010 keynote, a slate from HP.

Windows 8 -- with its touch-friendly interface designed with tablets in mind -- was aimed at giving the Windows tablet a boost, and manufacturers tried out new form factors, such as this Lenovo IdeaPad Yoga 13.

The snappily-titled 'Surface with Windows 8 RT' (mostly known as the Surface RT) was the first device to arrive as part of Microsoft's most recent attempt to build its own tablet hardware. Running the slimmed-down Windows 8 RT operating system, it was aimed at consumers, coming in at the same price as the iPad.

Because it ran on ARM chips, the Windows 8 RT operating system couldn't run normal desktop apps -- only ones downloaded from the Microsoft Store.

Reviews varied, although it won some admirers. However, Microsoft massively overestimated demand for this model, leading to a $900m write-down to cover the cost of unsold inventory. The RT was later dropped by Microsoft which focused instead on the Surface Pro models.

The Surface with Windows 8 Pro was the first business version of Microsoft's tablet. Running the full version of Windows 8, its high spec and higher ultrabook-style price means it is aimed firmly at the enterprise market. Our reviewer liked the build quality and the performance but said it was let down by battery life.

The Surface 2 arrived a year after the first model, and features a dual-position kickstand that angles the display at either 24 degrees or 40 degrees. While our reviewer liked the bump in performance over the Surface RT, the lack of apps remained a sticking point.

This is the Surface Pro 2 which arrived in October 2013, powered by a fourth generation (Haswell) processor, which delivered a improved performance and battery life over the original model. It features a dual-angle kickstand with the aim of making it more comfortable to work or watch video. Our reviewer liked the performance boost but said the unchanged chassis design "feels bulkier and heavier than ever."

Of course Microsoft wasn't the only one making Windows tablets -- here's the 8-inch Toshiba Encore from 2014, which runs Windows 8.1. Dell's Venue Pro 8 is another contender from this period.

The Surface Pro 3 from 2014 is a 12-inch Intel Core i7-based device with a 2,160-by-1,440-pixel screen and an adjustable kickstand. Microsoft promoted this device as "the tablet than can replace your laptop." Our reviewer concluded that: "Hardware niggles and price aside, if you need a Windows 8.1 computer that's flexible enough to be a tablet, a laptop (if you add the optional Type Cover) and even (if you add the optional Docking Station) a desktop PC, then the Surface Pro 3 manages the trade-offs as well as anything on the market."

Panasonic's huge 20-inch Toughpad FZ-Y1 Performance 'business-rugged' Windows tablet is aimed at CAD designers, engineers and architects. At £3,180 it's not cheap but what yu get is a large-format Windows tablet with a 4K touchscreen, an Intel Core i7 processor and a workstation-class discrete AMD FirePro GPU.

Surface Pro 4

The Surface Pro 4, released in October 2015, features a similar design to its predecessor but a slightly larger screen (12.3 inches versus 12 inches for the Surface Pro 3). It also has a front-facing infrared camera that uses the Windows Hello feature to authenticate a user based on facial recognition.

HP's 11.6-inch Elite X2 1012 is another two-in-one hybrid, which features a kickstand-based design that is reminiscent of Microsoft's Surface Pro 4.

Surface Book

This is the Surface Book, a 2-in-1 laptop/tablet hybrid with a detachable screen. More expensive models feature an Nvidia GeForce GPU in the base, while the Intel HD Graphics 520 GPU is in the screen section, integrated with the CPU and available for use in tablet mode.

It's not only Microsoft pushing Windows tablet innovation. Here's the Yoga Book. It's a 10.1-inch tablet/laptop hybrid which, instead of a physical keyboard, features what looks like a blank slab that can be used either as touch-based keyboard or for stylus input. Lenovo calls this component the Create Pad.

It's hardly a tablet in that you can't carry around it, but Microsoft's Surface Studio is a big all-in-one desktop that can fold down to enable drawing, typing, drafting, and other tasks, thanks to what Microsoft calls its "zero-gravity hinge."
