The only issue I have, which is similar to what I see with some other providers, is that the first non-free plan is a huge jump in storage space and price. If I want a Dropbox replacement, I'd be looking at a 25GB or 50GB plan (just comparing what I have with all kinds of free storage bonuses accumulated over years). Having some more "in-between" plans that are more linear in storage and price would've been an incentive to try this out since I'm not willing to fork $49 a year for 500GB while knowing that my Dropbox usage is less than one-tenth of that.
