I'll now travel with a sense of security
Why would that make me feel more secure? I've always been worried about my laptop getting stolen, stomped on, dropped or just failing. If I'm setting out on a two week trip - that would be fatal - I wouldn't be able to complete the trip at all. The laptop represented a complete "single point of failure" with no backup.
What I've done (and tested of course) is to stage on a 60gb external USB disk (tiny disk, takes no room really)
- a copy of all of my presentation material
- VM's (virtual machines) capable of running the demonstrations I have
- an installable copy of power point (just need the viewer really)
- an installable copy of the free VMWare player
I'll pack the disk separate from the laptop and if one or the other gets destroyed - as long as I have access to one of them - I'll still be good to go. Sure, I'd need to borrow a laptop/desktop in order to install VMware and to project from - but I'll have everything I need to go.
You should check out the VMWare player - they have "VM Appliances" freely available as well. Very nice if you wanted to play with Ubuntu or so other Linux distribution. These are pre-configured OS images with "single purposes" typically. For example - their browser "appliance" is an Ubuntu virtual machine configured with a browser as a standalone environment. The browser appliance lets you surf without worries about adware/spyware and protects your privacy (as the VM can be set to reset each time, as if it were the first time you were using it). Very nice - part of a much larger list of VM's you can play with.
Oh, and this is good for a laugh. David Letterman presents a "tribute" to Bill Gates.
