I like the fact that with raid 1 you can pull out a drive, stuff it in another machine, and, hey presto you can access all your data. You see, you don't have dependencies between your drives.
However, what craps me out about RAID 1 under Linux is that if you have to power down without shutting the system down nicely (yes it does happen, my system has been known to crash), then this causes the drive to get out of sync. Linux then requests a resync which involves resyncing the ENTIRE drive - during which time ALL your data is unprotected. This has happened to me on a number of occasions. With drive capacities being so large (a good thing) the resync times can take an age (not good).
Anyone found a way of getting Linux to only resync the blocks that got out of sync - I'm assuming this will be possible once snapshotting of volumes is available.
I currently use GPRS extensively on trains (admittedly in the London area where reception is relatively good) with no real speed issues. I'd be hard pushed to spend 4.95 GBP on GPRS connection charges during a typical journey.
if apple start bundling iTunes with OSx (maybe they do already, i don't know i'm not a trendy mac user) does this mean they'll start being investigated by the anti competition crew
This really needs to be platform independent for it to reach critical mass. I can see the appeal, but until something compatible is implemented on Windows, OS X and Linux, etc. this will not be adopted.

Does this mean we can look forward to delay effects normally associated with international calls when making local calls?

That'll be because at today's exchange rate a penny *is* worth 2 cents!
