Lenovo's signature business ultraportable, the ThinkPad X1 Carbon is now in its 5th generation, adding new Intel Kaby Lake processors and a larger battery without sacrificing portability. Having used this laptop for a few weeks now, it's clear that Lenovo's minor year-on-year improvements have led to a stunning device that's the best ThinkPad ultraportable yet.

The Thinkpad T450s is Lenovo’s latest addition to the legendary Thinkpad T series. This update brings Broadwell and several other refinements, but most notably a much needed trackpad redesign. An ultrabook aimed squarely at professionals, the T450s carefully balances portability, power and features in a semi-rugged 3.5 pound package.

What makes a product iconic? Design, functionality, styling, and innovation will get you part of the way there, but the true tests are how these products distinguished themselves from their competitors, how widely those traits were imitated by those competitors, and how history remembers their status. Here are some products that left their mark on the PC industry, whether in the form of full systems, CPUs, graphics cards, motherboards, cases or peripherals.

When Apple's very first iPad hit the scene in 2010, their take on the "modern tablet" was destined to become ubiquitous: a thin, rigid slab of touchable electronics covered by a sheet of shiny Gorilla Glass. Following the iPad's resounding success, Apple made no apologies for designing their tablets as though they were giant smartphones -- or at the very least, something less than a full-fledged computer.

Consider this though: Windows 8 Pro on a tablet challenges this mindset.

Lenovo has expanded their line of computing devices to include tablets. The company introduced two new slates earlier this year – the consumer-oriented IdeaPad K1 and the business-minded ThinkPad Tablet that we are examining today.

We've come to know Lenovo as one of the premiere business notebook manufacturers over the past years. The foundation for its ThinkPad line has been a uniform style that's stood the test of time quite well. It's simple, practical, recognizable and instills the value of quality in the minds of many. It'll be interesting to see how that tradition has carried on to their first ThinkPad tablet running Android.
