Mac. Used Windows for years and decided to make the switch when I found a good deal on a Macbook. As for the BlackBerry experience with it? Awful. BlackBerry Desktop 1.0 was unusable and I had to deal with it for months until 2.0 finally came out.
windows 7 ultimate for my desktop, windows 8 (beta) for my laptop
mac`s are way too overpriced for what i need specwise, plus no themebuilder for mac lol
to give the `overpriced` bit some creedence, an apple pro (the desktop not the laptop) of the same spec as my home pc would be over $6000, and i dont even use pc monitors.
I cant stand windows at all. I just have a copy on BootCamp, just so I can load leaked OS's on my BB, thats about it.
I use Windows on a crappy netbook for the same purpose. I wouldn't mind a spec'ed out Windows machine to run Adobe CS5. My 2011 15" mbp is choking on doing 12 x 8 feet banners in PS :/
I no longer use Linux, I was very close to being an All Linux household until Windows 7. (Windows 8 MAY moved me to a 50/50 Linux/Windows...)
Now I'll admit I have 3 customers whom I HATE having to send emails to because they are Mac Based shops and ALWAYS require special formatting vs the rest of the Windows world, so my belief that I need to use Windows because I have work to do is as much my preference as it is the OS of business, just as English is the dominating language of Business. Windows/MS Office are the dominating players in the Business world, and if you have little time to tinker and need to get things done it is a time saver and your best interest to use those tools.
Win7 HP 64-bit, Mint Debian 64-bit (with XP Pro VM), Fedora 15 64-bit on desktop; LMDE 64-bit, Fedora 15 64-bit, Sabayon 64-bit on netbook. Also use Linux Mint 11 just so I can have BURG for a bootloader without using straight Ubuntu (Linux Mint is as close as I'm getting) and suddenly developing the ability to compile properly 1st time around.
I don't think anyone was saying you can't get work done on a Mac. It's just that the majority of the business world is Windows based, and have programs developed for Windows. So naturally, Windows is the choice of OS for business use. Not to mention Windows computers are a lot cheaper than Macs with comparable specs (for the most part).
