Same has been said by many a people about Vista, Windows 7, Windows 8 and Windows 8.1. Truth is at the end of the day when MS have a small or any screwup the open-source crowd are so divided among themselves that they can never seize the opportunity.
The last Windows I used was Windows 2000. They crossed the line with me with forced registration and remote disabling "features".
Why anyone would use a OS that has this for anything mission-critical, is totally beyond me.
In my book Windows is a Toy, an elaborate gaming bios, and the only reason to use it is if you're into frontline hardcore PC gaming or need to use a professional application that only runs on Windows - such as Solid Works for engineers or something like that.
I've been riding Mac OS X since 2004 - for professional Flash development back then - and x86 Linux since 1999. Nowadays there is absolutely nothing aside of perhaps some neat Photoshop plugins that Linux and FOSS can't offer that I need for my professional work (Dev, Software Architect and Consultant). I expect that to improve even more with Gimp 3.0. I've got no incentive to replace my broken Mac Mini now - albeit HW & SW integration with Apple is still top-of-the-line.
However, I *do* still use a MS product: The last iteration of the XBox 360. The system mature to the marrow and has dirt cheap top gametitles out of the bargain bin. Just added Diablo 3 to my collection for 20 euros last saturday. Neat.
I hope Windows, the abysmally shitty Outlook Groupware, Exchange, MS Office and all those ancient crappy MS monsters die in a fire and/or gets squished by Google and Chrome OS like a bug. They would deserve it.
Google has users by a leash too, but at least I get all their stuff and services for free and have an interest in keeping them running and synced across devices no matter what.
Which is why I recommend Chrome OS over Windows whenever a n00b asks me for advice.
My 2 cents.
