Apple Macs are designed for function as as well as form these days and in my view stand up to scrutiny and outperform the PC on most criteria, including speed, mobility, lack of virus susceptibility (a real bonus) and most importantly user-friendliness. They are designed from the user's perspective, and as a result, I operate my entire small-medium enterprise business from the latest Apple Mac Leopard platform, which by the way you can also run XP (and possibly VISTA (someone confirm??)) through BootCamp, so if necessary you can switch between the OSX platform and a PC platform - two for the price of one! Therefore, the idea that Macs are only for the creative sector is simply a historical legacy of perception that Apple still has to overcome. The only thing we use a PC for nowadays is our business banking software which can only be used on XP (and we could use Bootcamp if we wished), but that says more about our bank than it does about Apple!
I work in IT designing Windows based server systems, run several linux boxes and use PCs and Macs at home. If you want something that just works, it's a no brainer IMO - go for a Mac every time.
Yes they can be more expensive than a base level PC but the hardware build quality is much better (I have never bled in a Mac, every PC I've ever owned has cut me to pieces when I get the cover off), the software is more reliable and the OS is just plain easier to work with - there is a reason why most PC manufacturers supply machines with Vista installed and offer XP as an "upgrade".
Having said that, when I purchased my twin CPU G5 PowerMac I specced up a roughly equivalent PC from Dell and it was 700 quid more expensive so the price differential isn't true in every case.
I have never had an issue getting a Mac to do the tasks I need it to do. There isn't the range of software to be sure, but what is available tends to be of a better quality. If you want a better range of software, install Fink then the world of Linux software opens up for you. If you want office, download and install X from apple and install Openoffice - free and compatible with MS Office.
To me, it's a tool. All tools require a level of maintenance to keep them working, but Windows just needs too much TLC to keep working reliably
I own up to being a "Mac Boi". I rarely use a PC so I don't know if what follows also applies to a PC.
My mac has NEVER crashed. Occasionally a programme freezes, but it does so without freezing the other programmes I am running. I am able to force the one programme to quit and carry on with the rest unharmed.
I don't know if this is the case with PCs, but I do hear a lot of complaints about PCs crashing and having to be rebooted.
I've never had a virus issue.
I was able to set it up straight out of the box without having to spend hours reading instructions and loading programmes. I automatically receive regular updates from Apple so it is always up to date, and they know exactly where they have to be on my mac and find theirown way there. It's all just so intuitive. It just works.
Yes I work in Design so for me there really is no other option, but I'm also able to run MS Office with no problems and work with PC colleagues seamlessly.
Oh, and Macs are just so damn sexshy <in a Sean Connery voice>
