1: Trust: Google is primarily in the business of search, and Google Drive is one of many other products that Google has. The company has a history of deleting or ignoring products that are not performing, or even that are performing but not core. Meanwhile Google's core business or searching anything and everything makes their motivations for GDrive suspect. I moved my email from Google long ago for similar reasons.

2: Salience: Dropbox is in the business of providing the Dropbox service - and everything else is non-core. So if I pay for my service at Dropbox I would expect to be more important to them than to Google, who make far more income from advertisers. Meanwhile Google is famous for being hard to do business with for customers of all levels.

3: Simplicty: Dropbox just works, and very elegantly. It's the product of choice for a very large number of people and SMEs and getting it working outside of a corporate network is easy. Meanwhile Google products (and Hangouts is the worst here) are often inaccessibly appalling to operate for people who are not deliberately immersed in the Google ecosystem.

It's not perfect. I would like to see a far higher standard of security from Dropbox, and wish they had not wasted so much effort on non-core functions like photos. This trend appears to be getting worse - with the article stating "Dropbox intends to offer software that businesspeople use for hours each day to create content and get work done."

"There is no Drive app for Linux at this time."

Meanwhile three years ago the message read: "Drive for Linux isn’t ready just yet"

Google Drive botches POSIX file permissions (e.g. it'll randomly/silently drop the execute bit for scripts).

For that kind of money, one can get a five-pack Office 365 with one TB storage and MS apps thrown in for each user.

(Unless MS changes their mind again - they already did last year, stiffing Lumia customers, and so I bought a NAS instead of signing up.)

Does it have an official Linux client?
