Hi 
This is all pretty fantastic! Congrats to anyone involved.
Please can we just drop all the threads that have an Urmas in them? Just
ignore the obvious FUD and avoid engaging.
If doing a migration with any kind of assessment of hardware requirements
or with any advice from almost anyone familiar with OpenSource then it's
highly likely that little or no new hardware needs to be bought except
where hand-helds are seen as more useful than a desktop.
Without guidance people might have ended up buying new kit but will soon
find that new kit lasts "forever". Staying with proprietary systems means
fairly frequent hardware upgrades just in order to keep doing the same
stuff. If people have upgraded to new hardware they will also begin to
realise they can bring the old stuff back into use, or give to worthy
causes such as those with charitable aims.
Regards from
