You should contact Adobe directly and see if you can “cross-grade” your current Adobe products to the current Mac version. It is usually possible for a fee.
Fusion is a nifty program. For someone like me it is a license to fiddle. For someone like you, probably not going to be very useful. Bootcamp is the method by which Apple enables people to reboot their machine into Windows. It involves actually partitioning the drive and installing Windows on the partition. It is not an emulation environment and it literally turns your Mac into a Windows PC (the Mac OS can’t be accessed when booted into Windows). Kind of nifty if you’re waiting half a year before making the switch over to the Mac OS.
I would recommend getting some lessons at the nearest Apple Store. You should drop in and ask them some questions. Highly recommended. If you get somebody who just wants to sell you something go for a walk and come back later. Majority of Apple sales people are helpful and not hard sellers. Sales happen because people are happy with the service, so the philosophy goes.
Good luck.
As to the rest of it, I'm kind of on overload and it's hard to cope with too much information. Rather that bootcamp and partition, I'll go with Fusion when I can get to it because I think you don't have to reboot with that. But the imac boots fast compared to the pc.
But in hindsight, it would be a whole lot easier not to even attempt to run Windows on the imac. There is a little more software for windows than for the mac. I wanted to get my sister Rootsmagic so we could share info, but they don't support mac. Rootsmagic was the only one I could find that would read my .fow files from my Family Origins software which quit working right when I loaded it onto this pc. It won't export gedcom files any more.
I think the nearest apple store is 100+ miles away. I'll just get the apple care and let them help me over the humps. Never needed it with Windows, but I started from the ground up and wasn't doing much other than saving and trading genealogy information. Then I got a genealogy program, then got into graphics and photography, fractals, started building simple web pages, upload lots of photos via ftp, that's mostly what I do now. The only reason I bought the imac when I did was that I know the days are numbered on my pc before it crashes. Now it just keeps rumbling along. At least I won't have to make frantic choices with no internet when it does crash and will be forced to tackle the imac.
Oh, there was another huge factor. At some point, no hurry, I wanted to upgrade my camera. 15 mp files, huge, not enough room left on my pc, need to cull out some photos I don't really need to keep. Right now my 20D only has 8mp files. So I wanted to do the computer end of it first and be prepared. I've got most of my files backed up but need to do a few more. As long as I can maintain an internet connection, there is help there, but I have to take it one baby step at a time. Right now a lot of it goes over my head.
