Since 1986. Saw the light after doing spreadsheets in DOS using backslash commands. If you believe the stories Apple is the largest selling BRAND of computer. Think before you flame that statement.
Currently using a Titanium G4 500 Mhz. Bluetooth wireless to an Ericsson T39m mobile. Can go online in most places in Europe where there is GSM coverage with GPRS. Cost is based on quantity not time - speed is as much as 64 k which is faster than dialup.
Running OS 10.2.2 Jaguar. Rock solid. Even have OS X running on an old G3 266 Powerbook and it is entirely acceptable. Clock speed isn't everything. There were rumours running that OS X has been run on the Intel platform. I say don't bother let them suffer.
Ever wondered why there is no support industry for the Macintosh? Obviously doesn't need one.
CASA - there's a can of worms on it's own. Interestingly their Regulatory CD is Intel, Mac and Unix. Mind you it is an Adobe product. There are some smarter people in Seattle than others.
BTW - Unix is like living in a teepee: No windows, No Gates, Apache in house.
