i'm looking at installing a computer in my post office shop to provide internet access to the public in the UK. I have a business broadband connection on order and am permitted to provide this as a paid or free service. I'm comfortable both with Tiger/Leopard and XP, although am much more well versed in XP when it gets down to nuts and bolts. What I'm wondering is whether an iMac would really be an ideal solution. I have a new one at home and love it to bits, but I'm not sure how lock-downable it is, both in terms of physically locking it down to prevent theft and locking down the OS to prevent any sort of hackery. I heard recently about Windows Steadystate on the Security Now podcast and that sounds like a really nice solution. The machine is reset to the default each time it is rebooted. But I want a Mac... So, is this something that could work? Would using some sort of VM be a more secure solution, or can OS X Leopard be locked down tightly? I would most likely get one of the Rain Design iGo stands for chic and minimal space usage. Any comments?
