At my day job I made the fateful decision to go with an all Apple shop. Everyone has an Apple MacPro maxed out with dual monitors (we don't buy Apple monitors or RAM because of the excessive price). (Some of the team have switched their machines to run Windows XP or Windows Vista and one team member uses Ubuntu; the only person on PC hardware is the CEO).
For mobile users we have a range of laptops including the MacBook Air and different generations of MacBook Pro and one MacBook. We even have an Xserve as our main server.
But there's a price to pay... when connecting laptops to the projector in the meeting room we are in adapter hell.
To solve these problem I have one of each adapter with little stickers on them. One end of each of these is a standard 'VGA' style connector for the projector.
The red is for MacBook Air, because it has a micro DVI connector.
The green is for the MacBook, because it has a mini DVI connector.
The yellow is for the recent MacBook Pros, because they have a mini DisplayPort connector.
The blue is for the old style MacBook Pros, because they have a Apple DVI connector.
Oddly all these machines manage to have the same MagSafe power connector, but I'm in video connector hell. When is someone going to do a wireless video standard?
