There has been a massive increase in the number of thin and light 13.3in ultraportables coming onto the market recently. We've seen the likes of the and , the and of course the to name but a few, not to mention all the new models we saw at IFA.

Durable and rugged; Gorilla glass screen protection; Spillproof; backlit keyboard; Excellent connectivity

Not the slimmest or lightest; Weak battery life; No IPS screen option; Reflective screen

If you are looking for lightweight, thin and small size without sacrificing hard drive space, this is the laptop for you. I previously had a Samsung Series 9 and thought that was a nice laptop, this is even nicer as its easier to type, has a better keyboard and touchpad.

The X1 Carbon that Lenovo shipped out for review is likely the fastest Ultrabook yet. The Broadwell Core i7 is certainly a step ahead of the other devices we have tested, and the included PCIe SSD is basically the fastest drive offered today.

The ThinkPad X1 Carbon Touch is attractive and solidly built, with an excellent touchscreen and a great keyboard. However, we'd like to see more ports and a removable battery at the very least. As it stands, this ultrabook is too expensive for widespread deployment.

Attractive design; Solid build quality; Superb touchscreen; Excellent keyboard; Fast battery charging; Mobile broadband with wireless hotspot support

Only two USB ports; Non-removable battery; Proprietary power connector; Expensive

A great business laptop. I wouldn't get it as a personal though. All of the things that you want in a business laptop with none of the creature comforts of a full-sized personal.

Great business notebook; Super thin, super light, fast; I love the feel of the keyboard; The battery charges fast and the display is nice; DisplayPort for the home dock, solid state drive, user friendly feeler pad, blue tooth, 3G sim card slot, usb 3.0, and dual band wifi.

Being so small, the feeler pad is directly under your palms; I had to get used to the feel of that; The charger port is fairly large, about usb sized, which can be mistaken for a usb port in the dark; That is something that you just have to get used to; The battery advertised 8 hours, I think.

Lenovo doesn't clear the field without a fight and, in our opinion, again faces the customer with a premium and virtually complete business ultrabook . The competition has failed to release an equal, mobile slim device to date.

High CPU and application performance; Light; rigid casing; Quiet; even relatively quiet during load; Big touchpad; Integrated 3G modem; Backlit keyboard; Feedback strong input devices; Good battery life; Short battery charge time; AR coated touchscreen; Unobtrusive; handy; very portable and yet as...

Tight viewing angles compared with IPS; CPU throttling during extreme load; Few interfaces; no docking port; High price; The matte touchscreen is top-notch compared with direct business contenders.

The Lenovo ThinkPad series is currently celebrating its 20th birthday, and today we have their new ThinkPad X1 Carbon on the chopping blocks. After all these years still producing some of the best business and casual laptops available the X1 Carbon looks to improve on its older sibling, while...

The Lenovo ThinkPad X1 is clearly a product for a consumer business, so a strong focus on quality, neglecting the design slightly. The strengths are a body strong and resistant to falls, an ergonomic keyboard and spill-resistant, the fingerprint reader to protect your data from prying eyes, HDMI,...
