I own one and yes, I can attest that it gets very, very hot on the surface. However, almost a year in, and it hasn't missed a beat. It therefore does not bother me. Besides, my cat loves it.

@DZ-Jay My cat loves my Time Capsule too! :-) And my media player (Mac Mini).

And to keep this on topic, the Time Capsule does precisely what it says on the tin. I can't recall precisely when I bought it, but I'd guess it was last summer.

I can heartily recommend TimeMachineEditor ( http://timesoftware.free.fr/timemachineeditor/ ) so that Time Machine only runs backups twice a day, as I found every hour excessive.

Yes -- it is very nice not to have time machine kick in and start backing up some multi-gigabyte VMWare Image that you happen to using that day.

Err, well the main point of it is that it's a backup.... if you're not backing up at the moment, you have precisely no redundancy, if you backup to a TM, you have a complete backup. It's unlikely (but possible and statistically little different) that both devices would fail at once... however, even with RAID both discs in that could fail at the same time - again, somewhat unlikely but still entirely possible.

For me it's great and as above, hasn't missed a beat at all.

@fifi agreed that its not more resilient and I don't own a time capsule, however I use timemachine on a firewire hd with my mbp and its proved to be a lifesaver on more than one occasion when I've either accidentally deleted some work or needed to roll back and it wasn't in vcs.

Having some form of backup is better than none, although raid is obviously far far better.
