Dell today announced the launch of its Sandy bridge-powered XPS 15z ultra-thin laptop. Touting the now defunct Adamo’s spiritual successor as the thinnest 15-inch PC in the world, the company announced that the XPS 15z is the “first in a series of new thin, ultra-powerful laptops from Dell this year.” Let’s hope that the new series does not share the same fate as the Adamo. And on that optimistic note, let’s just hit the jump and see what the specs have to say.

Apple recently overhauled its MacBook Air range. All the new models in its ultrathin notebook range only feature solid-state storage, providing them with obvious speed advantages over previous models, but severely restricting their built-in storage capacity – 13.3-incher with 256GB storage (maximum) costs $1600.

Even though many votaries of the cult of Apple might even find the Air’s storage plenteous, but a media junkie will not have any trouble expending the built-in Flash storage. Of course, you can always opt for a portable HDD.

But not any ordinary external drive. Hitachi is hoping that MacBook Air and Pro owners will opt for its new G-Technology G-Drive, the thinnest 2.5-inch external hard drive in the world. Formatted for plug-n-play compatibility with Macs, the G-Drive features the rugged Hitachi Travelstar Z5K320 drive inside.

The 320GB USB-powered drive has a MSRP of $99.99 and is available online and at Apple Retail Stores.
