i know schools are not a small business...but more and more schools are joining the mac world every day and with iPod touch/iPad they are jumping into it faster then ever.
I will give you this much...
*If* Apple can maintain the inroads they've fostered in the education arena... sooner or later the little urchins that spewed from our loins will be running companies OR... find themselves in a position to dictate where tech dollars are spent with said companies.
Still won't be enough of a tidal wave to compete with mass market competition that keeps PC components priced lower though.
And besides, there's nothing wrong with anyone who uses PC's/Androids/Blackberry's in small business. They get the job done just as well - for far less capital
In a nutshell, there is no compelling (read: financial) reason to move to Apple products on any kind even on a small scale. When everything works "basically" the same... the cheapest bid will always win.
I wouldn't be surprised if this "joint venture" crap isn't just something an Apple Exec pulled out of a retail store employee suggestion box.
