Hi all, Currently I use an old windows PC and CS3/Bridge. Would love to switch to a Mac and start using Lightroom 2. To cut to the chase, what do you think is the most inexpensive way to get a Mac that can run LR2? Obviously for new/refurb hardware it's probably the mini. For a used Mac, how old do you think is acceptable to run LR2? I am not that familiar with historical Mac hardware. I would like a desktop and hopefully running Leopard and iMovie acceptably, too. I could plan to upgrade again in about 2 years time, I just need something to get me through the next 2 years OK. Thanks!
