1) keep in mind you must add, windows XP or another windows OS,
its not included and remember XP or other OS is attached to just one computer so keep that in mind. You must enter the long, long activation code
2) there is supposed to be bridge that permits you a doc using your printers with mac software.....I found it does not work
3) I downloaded XP drivers for the same printers....I found it did not work
4) Using I.E. I found that using my company's website..I would lose the connection and get page not found.
5) I got error messages when I tried to download Firefox so I had to download the windows version from Mac and then drag and drop it to the XP desktop & install this way.
I have been using a mac since about 1996 and this is the worst software I have ever bought and has to use their tech support multiple time.
I personally prefer VMware but its really personal preference at this stage. Parallels brings a certain number of strengths and weaknesses to the table, and Vmware (and VirtualBox) has their own strengths/weaknesses as well.
Both Parallels and VMware offer a trial period, and VirtualBox is free so try all three.
I found crossover to be too limiting as what actually runs and problematic so I wouldn't recommend any crossover or WINE variant.
I've been reasonably happy with Parallels with XP but I don't push it too hard. Mainly run simple apps that have no problem, MS Office (Access), and Visual Studio. I have 8gb of memory and Parallels is the only thing that causes me to wish I had more.
Bootcamp is another option, I ran it on my old MBP since it only had 3gb memory. Rebooting was a royal pain. Wouldn't be as bad now that I have a SSD but I prefer being able to access my Mac apps when I want.
I did not have any luck with CrossOver. It does give you the ability to run Windows software without Windows but some speciality programs did not work. Might have been database related though. I didn't dig into it too much.
