Microsoft's Surface may be a little late, but it's still happening. While it might seem unlikely that any significant aspect of the device/environment was actually invented at Microsoft, given how well it performs in demonstration videos, it still marks a positive turn in the company's approach to personal computing, and as such something to be applauded.
For those less inclined to be charitable, there's this four year old opinion piece from MacDailyNews, which compares the propensity to defend Windows and make light of Macs to Stockholm Syndrome, in which victims come to identify with and defend their victimizers. If that viewpoint had a gram of validity in 2003, it's practically indisputable now, what with Vista being widely rejected in the market and Leopard about to gain its sea legs with the release of 10.5.2.
I just goes to show that life isn't so simple as any partisan would have it.
