Businesses are being forced to upgrade their software. Microsoft has
required all new software purchases to come with a license that
requires periodic upgrades (on Microsoft's schedule). Further, Microsoft
has dropped support for older versions of Windows (3.1, 95, 98, NT, 2000).
This leaves businesses trapped into either using unmaintainable software
or upgrading even though it will severely impact the business. Linux
gives you the freedom from this.
