Lenovo's buttoned-up Thinkpad X300 ultraportable notebook computer may not have the Apple MacBook Air's superslim Spartan style, but after firing up the X300, it's hard to not love this laptop.

From rock-solid construction to piled-in perks, the Lenovo ThinkPad X300 is a biz-centric beast that provides just about everything that matters to the modern road warrior.

The Air and Lenovo ThinkPad X300 do have some similarities. They both have crisp 13.3in displays (although the Lenovo ThinkPad X300 has a higher resolution - 1,440x900 pixels vs 1,280x800), and both offer 64GB solid state drives (An SSD comes standard with Lenovo's machine, but tacks about $1,000 on to the Air's price tag; if you equip them similarly, the two notebooks cost about the same).

Whether you're afraid of dropping your laptop at the airport or accidentally spilling some coffee on the case, the Lenovo ThinkPad X300 is built like - and resembles - a black box recorder. The keyboard is spill resistant, and the textured carbon- and glass-fiber exterior is supposed to protect the innards; it feels good to the touch, too.

Now, technically, the X300 is a little chunky side for a true ultralight-a little over an inch thick and over 1.5kg (1.8kg with AC adapter) as opposed to the Air's 1.3kg heft. Then again, you can pop a disc in the ThinkPad's integrated, paper-thin, three-ounce DVD drive and actually watch movies as opposed to trying to stuff an external drive in with the Air in that manila envelope.

The Lenovo ThinkPad X300 has a decent amount of power for an ultralight notebook - in fact, it scored surprisingly well against other ultralights. With a 1.2GHz Core 2 Duo L7100 processor and 2GB of RAM, it scored a 64, outpacing the MacBook Air by a healthy 7 points in WorldBench 6 Beta 2 tests.

On the other hand, the Lenovo ThinkPad X300's performance is exactly average compared to the broad field of ultraportables we've tested. It posted an average score in our battery life tests too, lasting 4 hours and 22 minutes on a charge.

Another thumb in Apple's eye is the Lenovo ThinkPad X300's many features. Here you have a notebook not much thicker than Air but, not only does it manage to slot in a DVD drive, it also has three USB 2.0 ports, a VGA-out port for an external display, a webcam, headphone and microphone jacks, and an ethernet port. The Air has a webcam, but it has only one USB port, and you have to use an optional adaptor to connect via ethernet.

Speaking of options, the Lenovo ThinkPad X300 is probably the only ultraportable PC that gives you both a touchpoint and a trackpad. Obviously it boils down to personal preference, but at least you can choose. As is often the case with ThinkPads, the keyboard feels great. There's enough tactile feedback on the full-sized keys to allow quick, accurate typing.
