Tip: don't buy the old drobo, get the new one. Don't get the drobo share, use an airport extreme or similar disk-sharing network device.
Still, after seeing the corruption and after trying their support, I don't think I'll want to buy any more Drobo products ever again.
A one device solution? Well, that'd be a router, switch, hard disk... (can you say, computer?)
sometimes we want stuff that's single purpose, done well, easy on the power/heat/etc. I now have an appletv on a turn-off power strip, enabling me to 'turn on' the tv system and have something running easily, rather than having to get my laptop out, an external disk, try and make it all work. Ugh. madness.
It is a bit unsettling that Drobo advertises these are completely fool-proof in their marketing materials but support, rightfully I may add, recommends routine backups. In the end, it's a JBOD RAID in a pretty enclosure with approachable software. For me, that works.
All I wanted out of my DroboPro was a way to combine eight drives and have an expandable dual-disk redundancy array. It's working like a champ for that.
The point here is, Drobo/RAID/NAS are disk redundancy solutions - they cater for the fallibility of spinning magnetic platters, and never promise 100% reliability. Just like any solution, if you want to avoid data loss, you need to have an orthogonal backup system for when the other fails at a system level.
It sucks that he's had such problems with his Drobos, and it looks like the support he's got is subpar. This is not, however, the universal experience. Based on my experience, I'd be happy to recommend the Drobo to most people I know who want a simple and easy to setup solution for hard drive failures, with the big caveat that they still need at least one other backup solution.
