Firstly, don't buy the 'only inexperienced users would buy a Drobo' nonsense. I'm a very experienced and very computer literate user (I'm not biting by quantifying that!)
I have a Drobo and a Time capsule, for different purposes. The Time Capsule serves for backups to the Mac Pro. I use the data area on the time capsule to store SVN repositories for software development from the Macs and another OS I work with.
I also have a Drobo which is my massive storage media server, and secondary backup device for important / difficult to replace things (like my music collection and photo collections, which whilst not huge would be difficult (in the case of the amount of CD ripping to be done) or impossible (in the case of the photos) to replace.
The Drobo has pros and cons. The flexibility of expansion is a big plus and serves my needs well for its role. I am unlikely to need to use the full 2TB of Time Capsule space for the role it serves. Whilst very slow, I can happily expand the Drobo if I need. It can stream movie files for playback elsewhere in the house, and can perform adequately for backups.
The software is flaky as others have said. For some reason I cannot administer it from the wireless on my Macbook Pro (even though I can access its data from the same machine) and I have to do that from a machine on the wired network. That said you need to administer it rarely - it's not a toy!
So - if you need big, flexible but slow storage with data redundancy - great. If you need faster access or are likely to only need a couple of drives at most - there are better options out there and £500 goes some way towards a second hand Mac Pro with all the storage options you need and a few other benefits besides.
