No need to appologize for having a x86 PC running MS Windows98 and MS Office. Some of the rest of us also run x86 PCs and MS software.
My advice ... if you have the money available and enough room for two machines, keep your existing machine to run the MS software and setup the AmigaOne in it's own case to run Linux and AmigaOS.
If you wish, network them together. If you have a broadband internet connection, get an inexpensive router and use both machines on the internet.
