With you on this. May not be terribly user friendly, but securely storing things on 'cloud' services is only something YOU can do.
The last thing you want when securely storing data is some cookie cutter solution someone else designed.
I've written about this before.. I use EC2 myself, with OpenVPN for transit and truecrypt on the server to secure my data.
Is it perfect? No. It is easy to use? For the average guy? No. But I think it's easy to use, I run samba over the openvpn. Once set, its just a matter of mounting network drives and copying files. I dunno how you can get much easier. I also can't see how it could possibly get any more secure. Well, ok I could drop truecrypt and encrypt on my end so nothing is ever visible on the server itself in the clear (despite the server being pretty much inaccessible without the openvpn key) but that's not my aim. My goal was to have transit and storage encrypted and secure. All bets are off if someone breaks into the server (without rebooting it, if it gets rebooted, the truecrypt volume is gone until I come along to put in the key.) That was the level of protection and risk I decided upon.
And that's why you need to design a solution that fits your needs. Everyone's protection and risk requirements are different, and so you really should have a solution that's tailored to you. There's lots of free tools and most of them aren't too hard to use, in my opinion. But I've been around computers for 30 years, I find little of it 'difficult to use.'
