I’m a fan of Dropbox, it’s an excellent product. It’s the only file sync product I’ve used in anger that I actually trust — I’ve had glitches of one sort or another with iCloud, Google Drive, OneDrive... never with Dropbox. It just works. Apple should have bought them, Jobs got it wrong ;-)

Dropbox Paper is also a delight to use, from a personal perspective. I’ve never used it on a team. I would be interested to hear whether teams of 50+ have successfully used it — it just doesn’t feel ready for the enterprise in the way that Google Drive does/is.

I’ve not read this S-1 (perhaps it clarifies this) but Dropbox seems a little confused about positioning B2C vs B2B. Does it have a packaging problem? Can it have it both ways? It feels like it’s trying to, but when I was a paying Pro user, I couldn’t get away from the upsell on the site for me to move to the business package. Annoying.

Good luck to them though — they have killer design, a killer viral product and a loyal user base.
