If you've been as disappointed with Apple's lack of attention to the Mac Pro as I have, you may be considering a move towards Windows.
Unfortunately, it's difficult to just pick up and change platforms, with hardware and software specifically designed for one or the other. I've been on Macs for the past decade, but after today's "update" to the Mac Pros, the gaffe with Final Cut and Apple's increasingly consumer-oriented business model, I've decided to move away from their platform.
My problem is that I work on a Mac Pro in the office and a Macbook Pro for mobile/home work. The Mac Pro is due for an upgrade, so I'll be building a PC, but hanging on to the laptop. As a Mac guy, I'm not totally sure that I'll be happy on Windows, but CS5.5 is platform-specific, so you have to pick one or the other.
The tip is simply that when looking to upgrade to CS6, I noticed that the volume-license version is multi-platform, but the same price for a single license. So I did a cross-grade to a single volume license and now I'm free to build and install on a workstation PC, while maintaining a Macbook Pro for the time being. This is just a bit of insurance in case Windows doesn't work out :)
It's a simple thing but it made the whole decision to move away from Apple a lot more appealing.
Goodbye Mac Pro,
