>A review by an independent vendor (HP)
Are you serious? HP is Microsoft. 99% of their products run Windows and Micro$haft software.
He's what a M$ or a vendor pushing M$ products report will always include:
1. ** Retraining costs associated with migrating to Linux. This is basically where they claim all those additional costs will come from.
It's completely bogus though. Every new version of Windows or M$ Office requires retraining, and some might argue are even more of departure from the normal workflow paradigm than switching to Linux/Libre Office. Metro and the Ribbon alone are so far removed from the previous versions that the Linux desktop and Libre Office software are much easier to pickup. Thus it's more costly to retrain in M$ and their every-changing and radical UI overhauls than to go FOSS.
2. ** Document conversion costs. This is another bogus claim. How many times I've seen incompatibilities between different versions of M$ Office file formats. Safe to say, M$ doesn't include those costs in it's assessment of continuing to use its products.
Then there are the savings associated with migrating to FOSS:
1. Licence fees. There are none for software like LibreOffice.
2. Retraining costs are lower going from XP to desktop Linux than from XP to 8. The same applies going from M$ Office 2003 to LibreOffice than 2007+. Metro / Ribbon changes are so alien to users, it's like starting from scratch, whereas, the FOSS option is very familiar.
3. Hardware can be repurposed. There's no need to buy all new hardware when FOSS has lower system requirements than Windows.
4. No risk of malware, rootkits, NSA backdoors. The NHS just recently was infected with malware on their XP systems. You can bet that M$ never includes those costs when it sponsors ROI reports about migrating to FOSS.
5. Vendor neutral standards like ODF, and the plethora of office suites which implement it, guarantees future accessibility, and competitive prices for support contracts.
6. Security. All code can be audited unlike proprietary products from Micro$haft.
