While we await more Thunderbolt storage devices, Western Digital grabbed headlines not too long ago for the announcement of its 6TB My Book Studio Edition II Mac-ready external drive. The two-bay external enclosure features two 3.5" Western Digital Caviar Green drives and is available in 2TB, 4TB and 6TB configurations. The drives are priced at $249, $399 and $499 respectively although street pricing is significantly lower. I saw the drives going for $179 for 2TB, $303 for the 4TB configuration and $379 for the 6TB model at Amazon.

By default My Book Studio Edition II implements a RAID-0 across its two internal drives, although Western Digital's software lets you convert that to a RAID-1 (at half the capacity) if you'd like.

Apple has been playing it cool on the WiFi side of things lately. It started with the previous Airport Extreme (Gen 4) which quietly introduced three spatial stream support, followed up by the Early 2011 MacBook Pro update which brought a three spatial stream compliant WLAN stack, and now has continued with an even more understated update for the Time Capsule (4th generation) and Airport Extreme (5th generation).

How does this refresh compare with the previous generation? Read on to find out.

Mac OS X Server costs 5% of what it cost just three years ago. Whatever your needs and whatever the software’s shortcomings, this is hard to ignore. Leopard Server cost $999 for an unlimited-client license, Snow Leopard Server cost $499, and Lion Server costs $50.

For this reason alone, Lion Server will (and should) attract the attention of people who have never been in the market for server software before - home users, in particular - but it has to do so without alienating the business and education customers who currently rely on the software. These are Lion Server’s challenges: is there a real point in having it at home? And as a comparatively-dirt-cheap App Store download, is it lacking in features and power compared to previous versions?

Last week we published our review of the new 2011 MacBook Air. Both the 11 and 13-inch models ship with ultra low-voltage (ULV) dual-core Sandy Bridge CPUs, a first for the lineup. Also another first for the lineup is the fact that you can now get equally specced CPUs in both models. In theory you'd be able to have the same performance regardless of chassis size.

The 1.8GHz Core i7 is offered as an upgrade to both the 11 and 13-inch MacBook Air. With much higher max turbo speeds and another megabyte of L3 cache, it's clear this is going to be a big upgrade over the standard 11-inch Air.

Last week we got our hands on one of these upgraded 11-inch models to find out just how much faster it is. We also wanted to find out what sort of an impact the faster CPU would have on the 11's thermals and battery life. It just so happens that our upgraded 11 gave us more than just that to investigate.

I've always liked ultraportables. Back when I was in college I kept buying increasingly more portable notebooks until I eventually ended up with something horribly unusable for actual work. When Apple introduced the first MacBook Air back in 2008 I fell in love. It finally stuck a fast enough CPU in a small enough chassis and gave me a full sized keyboard to type on. I was set.

Last year Apple introduced the first major update to the MacBook Air, bifurcating the lineup with the first ever 11-inch model in addition to the standard 13. With last year's update the MacBook Air did so well that it actually started outselling the base MacBook. Apple isn't a fan of large complicated lineups so it retired the MacBook. If you want a portable Mac you can buy a MacBook Air or a MacBook Pro.

As the mainstream counterpart to the MacBook Pro, Apple had to do something about the performance of the MacBook Air. While last year's updates were great alternatives to cheap, underpowered netbooks, they weren't fast enough to be a mainstream computer in 2011. Last year's Air featured Intel's Core 2 Duo processors, based on an architecture that debuted in 2006. Intel has released two major architectures since then.

Just nine months after the release of the 2010 MacBook Air, Apple fixed the problem. Meet the new Air:

If these systems look identical to the ones they're replacing that's because they are, at least from the outside. With the exception of a backlit keyboard, some differences in the row of function keys and a Thunderbolt logo, these babies look identical to last year's models.

You shouldn't judge a (Mac)book by its cover, because the MacBook Air's internals are much improved.

Apple hasn't exactly paid a ton of attention to Mac OS X since the iPhone came out. There, I said it.

This was obvious even in the lead-up to Leopard in 2007, when Apple delayed that OS's release from a spring timeframe to October so that they could get the iPhone out the door. Since then, we've gotten Snow Leopard (a "no new features" release that did a lot to optimize the platform at the expense of aging PowerPC Macs) and a long string of point updates that have done plenty to polish the OS but not much to advance it. Using OS X today is fundamentally much the same as it was four years ago, though we're doing it on hardware that's four years faster.

Lion, originally unveiled in October of 2010, is Apple's attempt to get "back to the Mac," which when translated from Apple into English means that the company wanted to port some ideas and some functionality from iOS into OS X, which parallels iOS's journey from a touch-driven iPod interface to an increasingly OS X-flavored standalone OS. With Lion, Apple wants to do for its Mac software what it did for its Mac hardware with the MacBook Air - bring concepts people like in tablets to full-featured computers.

One of our goals with a Lion review, then, is to separate the actual useful features from the fluff - what has OS X borrowed from iOS, and does it really improve and make sense for the platform? What functionality feels grafted-on, and what feels like it's been missing from the platform for years?

Another important goal will be to determine the direction in which Lion moves the platform, because new OS X releases tend to be messages just as much as operating systems: Leopard, with its two-and-a-half-year development cycle, told people that OS X's fast-paced, sometimes chaotic early phase was officially over. Snow Leopard told PowerPC users to get with the times or get off the train (or, to put it positively, that Intel was the future and that developers needed to take fuller advantage of the architecture's strengths).

So what is Lion trying to tell us? Read on and find out.

One by one the barriers to mobile computing have been falling. In the early days you could move to a notebook but you'd give up a lot of CPU, GPU and I/O performance. SSDs really fixed the storage performance issue (2.5" hard drives are horrendously slow compared to their 3.5" counterparts), power gating and turbo boost helped address the CPU problem and I wouldn't be too surprised to see companies have another go at external GPU solutions for those who need the added graphics horsepower.

The idea of external GPUs brings up the current limitation we face in this mobile transition. Although being more mobile is great, we still want the best of both worlds: great performance when we're at a desk, and great battery life when mobile. Enabling the former is going to require new technologies as well as new high speed interfaces.

Intel has been at the forefront of many of the successful high bandwidth interfaces in the evolution of the PC industry. Will Thunderbolt be another feather in its cap? In February we got the first Thunderbolt enabled MacBook Pros and just last week Promise shipped the first Thunderbolt enabled storage device. It's time to put the two together.
