I use it for my business too. We have 4 different accounts and I am the only one connecting all accounts. If dropbox would offer an option to get 50 GB and create 10 accounts who can access different folders I would gladly pay 100-150 USD a year.
finally, I was about to drop dropbox because I am running out of space.
I absolutely love the service, but their prices are just 2-3 times above the competition. I would buy the 100 GB in a heartbeat if it would be 50-70 USD a year.

I am launching my first business right now, and last week my first son was born. As I work 90% from home, the 60 hours weeks don't interfere with my family time at all.
Funny, the I was on flippa.com for 2 hours today. I use the site to study how "repeat sellers" create hughly successful sites in a matter of months. I followed a tip from Glen Allsopp on seomoz.
I had no idea who Marc Andreessen was until this post. I clicked through to http://blog.jedchristiansen.com/2009/10/15/a-marc-andreessen... and discovered a whole new universe of "how to get funding" He seemed to have written some posts in conjunction with Paul Graham
