Virtualisation is taking me ...
... to the shop to buy more memory.
Professionally there is some merit in running VMs (after all, IBM has made a mainframe business out of it). Although not as much as the marketing bumf says: most of the benefits can be achieved by consolidating workloads onto a single server, without the overheads, administration and duplication of multiple copies of the same old O/S.
Where it does win is with my old mum. She thinks her XP 'pooter is running native! In fact it's running as a Virtualbox guest on top of Ubuntu 8.04. This, and VNC, does make remote administration and support (a must with m.o.m-s the world over) much easier as I can access the system underneath XP whenever necessary to reboot it etc. All without having to go though the joys of getting a 70 year-old, 150 miles away, to press the right combination of keys, buttons and wotsits in the right order while holding the phone, too.
 actually she doesn't care what it is or what it runs on - just so long as it works.
 not that age is a driver, work provides the same opportunities with 20-60 y-o's as well.
