POS-Ready 2009 could be a handy alternative. Let's hope there is a way to run MS-Office on that. MS-Office is the only thing that is stopping me from migrating to Linux. I used to use Openoffice and LibreOffice before(even on Windows), but since I have moved to MS-Office, I have been hooked. Totally worth it. Now, I can't imagine moving back to other office apps.
Secondly, can't run FS2004 or FSX on Linux.
