I myself, have converted two of my family members, and they are using Mint Bianca on personal and business computers. My father owns a scanning and printing/data storage business. The problems (and I don't mean to beat a dead horse here) with XP he had were unbelievable, driver problems, unable to use multiple printers/scanners, constant "spooling" errors, source not present errors. The list goes on.
After installing mint, we have not had one single error, and, (I don't mean to keep beating this horse) everything works, all three scanners, all three printers. Oh, and everything is easily twice as fast!!!!!!!!!!!!!
If it's Mint you're installing on their computer you can always rely on the Linux Mint Support Center for the support, and we'll support them so you don't have to worry about this.
I am unable to really give support to anyone I recommend to, only basics, as to my "green" knowledge of Linux. I have pointed my father to the Mint forum for some questions he has had, and has had them all answered by reading. On the other side, I have not had to offer any support, as to nothing has failed or faulted to offer support too!!!!
I also have my own business, and several pc's here for work and play, they all four have Mint Bianca 2.2 on them. I wanted to add, that I am recommending this OS, and am going to be continuing to do so.
What amazes me about Mint Bianca, first, is the diversity of Bianca, second, the the friendly and helpful people here.
I am not making a business on Linux, I just recommend what I see as the best thats out there for people to use. This is it!!!
