Hi. This is my first post. I am in full-on panic mode I am a very happy 64-bit Vista user, but I have been curious about Macs for some time. I have no prior experience with them. I finally took the plunge yesterday and got the 24" iMac/3.06GHZ/4GB/8800gs. I love the hardware and everything seems to run nice and smoothly. Of course, I don't have the slightest idea how this thing works, and I am freaking out. Now I have two expensive computers on my desk, and and my computing has become a confused mishmash between the two. I'm feeling like I've made a huge mistake. It's like I've suddenly got three legs and I'm constantly trying to figure out which two to use. Anyway, I plan to get a book on Leopard to see how it works. But I thought I could maybe ease things by installing Vista in the meantime. So, a couple general questions: 1) So Windows will really run well on the iMac? As in, it'll be just like using it on a PC? This really works and is stable enough run as a long-term solution on the iMac, should I decide that I prefer it to Leopard and want to stick with it as my primary OS? Maybe I could give my PC to my dad, if the Vista performance is the same or better on the iMac. 2) I understand that I can run Windows either by booting into it though Boot Camp. or virtualization with Vmware Fusion? I could have both options available to me on the same computer? And this would be considered the same installation of Windows for licensing purposes...so I don't need separate copies for Boot Camp and Fusion (I hope not)? 3) I mostly use an external HD for storage. Will this be a problem when switching between the two operating systems? Can I use files I've saved in Windows on the Mac side, and vice-versa? The data doesn't get flaky at all going back and forth between the two? 4) What about the mouse? I hate this Mighty Mouse. I want to use my regular mouse. Can I use it on the Mac? 5) I am confused about which version of Vista I may install on the Mac. It seems you can install 64-bit on some Macs, but not the iMac? 6) I see there is an update to Boot Camp. How do I find out if I need it, or what version I currently have installed? Thanks for the help. I'm sure I'll have more questions, if that's OK. I feel like I'm in a race against the clock to see if I can live with this new computer before the return period is up.
