All of this just shows the real difficulty in deciding to stick/switch/add...
You 'stick' if you're nervous/can't be bothered/arsed to think about the long term cost etc.
You 'switch' if you're not afraid of the 'dark' / feel reasonably technically competent (not that a Mac really requires it - but you feel better about the leap if you are)
You 'add' if you've got the time/money/inclination.
I help control 25 Macs and 100 PCs with 20 odd MS Servers and 2 OS X Servers... and it's the that Macs make the money
.
I like Macs 'cos:
I used them for 15 years (or is that 17?)
No registry
Nice GUI
No known viruses (so far)
Loadsa geezers writing funky/useful utils 'cos now they can... without a huge license to pay
Forums galore - previous writer is nearly fully right - MS forums can be a little thin on the ground - but if you want to know about MS Exchange Servers go to slipstick.com ;-)
ThinkFree Office is $50
I don't like Macs 'cos:
Technical documentation falls fully 'tween two stools - it's either childish or geekish.
Hardware cost is 'high' (get what you pay for guys)
If I don't reboot my Macmini at least once a week - the HD makes me pay for it. (XP up now for over 6 weeks).
I "can't" move my copy of OS X Server to an updated box - because that breaks the Licence Agreement
There's more I'm sure ;-)
And lastly I'll rant this,
I've really tried to be an evangelist about Macs to 'all the little people' (people I know and small businesses) who seemingly have the inclination to consider the alternative... but it's all about price right? Trust me, if that's how you qualify a product then don't waste your time trying to convert them... Move on.
Good luck with whatever you buy - I hope it does what you need it to do... "Peace Man".
