1. Windows is bad due to viruses and hang time, etc. Get a Mac so you don't have virus problems. Yet...Mac's have this BootCamp program so you can run Vista along with the Mac OS. Umm....wouldn't that now make my Mac just as vulnerable to viruses as my PC? Why would I pay more for a Mac under the delusion that it's hacker safe only to put Vista back on my system?
There's nothing saying that you HAVE to install Windows....Win7 is pretty cool, but I'll stick with OS X because I think it's a better OS for what I do.
Even if you do install Windows and you were to get a virus, it can ONLY affect the windows side - it can't harm your OS X partition.
3. I use MS Office Suite every day. MS Word, Excel, Access. I also paid a lot of money for Photoshop. Will I still be able to use all of those "professional" type programs on a Mac?
As a previous poster said, Access isn't available on the Mac, but otherwise you can buy Microsoft Office for Mac (Word, Excel, Powerpoint, Entourage (similar to Outlook))
As for Photoshop - Adobe has a cross-grade licensing program - You pay a small fee and they send you the Mac version of Photoshop after you sign some forms saying you've destroyed your Windows copy, etc. Get in touch with them for more details on that.
4. If I save a file on those programs at the university, can I bring my thumb drive home and open up those files? What about vice versa?
Yes, pretty much all flash drives are compatible with OS X, and usually even with Linux/UNIX as well.
Sorry for all the questions, but it just seems like all the articles I read rehash the same 9 or 10 basic, generic reasons (i.e. price, anti-virus, user friendly) on why to buy a Mac without specifically dealing with honest newbie concerns. I've had a PC since the DOS 3.0 days so it's very scary for me as a graduate student to think about what happens to all my very familiar programs, files, and hard work if I switch to a Mac. It's a big step.
I was a PC user since around DOS 3.3 myself, all the way up through Vista. Vista was the last straw for me. Even though I really enjoyed WinNT 4.0, Win2000 and XP, they all still had their issues, and Vista was the worst of all (WinME taking a close second place.)
I had been researching Macs for maybe 6 months, and finally decided it was the better way for me to go, and I haven't looked back. Of course, being so ingrained in the tech world, I have WindowsXP in VMWare Fusion for the rare time I may need to run something. I'll also be getting Win7 when it comes out (retail does have its perks once in awhile) just to keep up with what's going on with it.
The combination of UNIX security and stability, plus the ease of use and extremely low maintenance requirements is what really made the OS X experience work for me, and I'm trying to convince my parents to get a Mac as well - the lack of viruses and ease of setup will be so much easier for them.
