If you use linux like redhat they come with a lot of free open
source software that s compatiable with microsoft/Adobe software.
Use as a desktop purely for reading email and using word+excel is
good.
The bad is that if you need to install some special software to
connect to your office system like database running SAP or your
company's own in-house software then it will probably not work on
linux and you will have a problem.
