It is strange to say but, once in his life, Steve Ballmer is right.
Recentely he said that "Vista is still a work-in-progress OS"; today Popular Mechanics has posted a comparison between Mac OS X Leopard and Windows Vista.
The result is that Apple's operating system has blown away the unsuccessful and much criticized competitor: on Macs every tasks is performed faster, programs run quicker and even Windows Vista becomes more responsive than on a PC with the same technical specifications.
Last but not least, Popular Mechanics shows that Macs are even cheaper than most PCs!
Here is their verdict:
Mac: In both the laptop and desktop showdowns, Apple’s computers were the winners. [.....] In our speed trials, however, Leopard OS trounced Vista in all-important tasks such as boot-up, shutdown and program-launch times. We [...] found that both Apple computers ran Vista faster than our PCs did.
PC: Simply put, Vista proved to be a more sluggish operating system than Leopard. [.....] the Gateway One actually costs $300 more than an iMac. That means for the price of the Gateway you could buy an iMac, boost its hard drive to match the Gateway’s, purchase a copy of Vista to boot—and still save $100.
