[quote=CONCHO]I love that it is still double the price of OS X Mountain Lion.[/quote]

The upgrade from snow leopard to lion is $20 for all your machines running snow leopard… But if you have an older machine, they force you to upgrade to snow leopard first, I believe that’s for $60 per machine.

Honestly, I have a triple boot Mac Mini Server that does OSX Lion Server, Ubuntu 12.04, and Windows Vista (well the windows vista also can be booted virtualized with VirtualBox)….I honestly don’t use the OSX at all, except on the rare occasion i need to write someone for an iPhone app…The Vista is used because in practice there’s some software that doesn’t run on ubuntu…Other than that, I can do pretty much everything else in Ubuntu + work related stuff.

Can’t beat the $0.00 upgrade cost of Ubuntu (though you have to tolerate a lot of quirks with it)
