Oh, god, good ol' MS, serving up the chuckles.
'PCs just work'? HAHAHAHA. They only 'just work' once you've spent hours tweaking all the Control Panel settings, waiting for Windows Update to finish and restarting constantly, installing anti-virus software, installing an alternative browser to replace Internet Explorer and deleting all the cruftware that comes preinstalled on OEM computers.
This seriously does sound like something that's targeted towards current Windows users that are considering switching to Mac, rather than getting Mac users to switch to Windows. It is true that a Windows XP user will be more familiar with the basics of Windows 7's UI than the Mac OS X one, but still.
I've used Windows 7, and it made my computing experience a lot harder. Even though Win7 is better than some other Windows versions, I still felt as though Windows impeded with my workflow.
The productivity stuff makes me laugh. OF COURSE Macs can share work files with PCs—it's called MICROSOFT OFFICE FOR MAC. Most people I know who use Macs HAVE MS Office installed! I'm waiting for Office 2011 to come out, but still. Did the people who wrote this forget that Microsoft makes Mac software?
I think the only valid argument might be the stuff about Blu-Ray and dongles. And maybe the choice of different models—but none of them are what I want, because I don't want Windows; I want Mac OS X!
And, of course, Microsoft fails to mention that those Macs can run Windows, so there's no need to buy a crappy Acer or Dell to get that 'wonderful' Windows experience. If I have a need to use Windows, I'll just buy a copy of Win7 and install it with Boot Camp. No other computer needed. Can't say that about PCs—most of them can't run Mac OS X unless they've got similar parts to Macs, and Apple breaks the updates because of the EULA.
This isn't going to do anything. Office and Windows are considered a commodity. They're the 'default'. They wouldn't be doing anything if the Mac wasn't gaining on them. This is probably one of the first times since Windows came out that Microsoft actually sees another OS as a threat.
