Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Easy to use
You can use Dropbox via website, by installing a desktop client that creates a folder that you simply drag and drop files into, or with their mobile app. Everything synchronizes across all devices used and cloud storage. And Dropbox offers easy methods of sharing whatever is within it.
Pro Cross-platform desktop and mobile
Dropbox is available on iOS, Android, BlackBerry, Windows, OS X and Linux. By having a client for so many OS's pretty much anyone is covered no matter what kind of device or OS they are using.
Pro Allows sharing a folder
Using a desktop client: right click on the folder you want to share and select Dropbox > Share This Folder, then enter the e-mail addressees of people you want to share the folder with.
Pro Smart updates to big files
If a small portion of the file is changed it sends/receives only the differences (not the whole file), which is fast and bandwidth-efficient.
Pro Allows sharing a single file via link
Whether using desktop client or web interface, simply right click on the file you want to share and select Dropbox > Share link, then send the link to the people you want to share the file with. The recipient does not require a Dropbox account.

Dropbox personal accounts start out free, with 2GB of space, but users can get extra space by recommending the site to friends, or taking part in events like "Dropquest", where users can win extra space by solving puzzles.

Dropbox offers native Linux support, integrates with Nautilus file manager.
Pro Reliable

Pro Outline-style hierarchy with zoom

Interface has no clutter. It allows focusing on thoughts to note down. This keeps things simple and easy to understand, which can help keep everything organized in an intuitive manner.

OPML (Outline Processor Markup Language) is a commonly used standard for text exchange. With two-way support for OPML you are never locked into Workflowy. Importing/exporting via copy/paste of entire outlines is a snap.

Cons
Con Too little free space
There is just too little of free space available comparing to the competition.

Con Not secure
They don't apply end-to-end encryption, files are visible to admins, governments, etc..
Con No privacy
Extensive collecting and distribution of user data to commercial third parties.
Con Consumes a lot of CPU resources when syncing many files
Con All-or-nothing (non-selective) upload
Uploading generated contents (cache, compiled code, etc.) is prone to conflicts, wastes bandwidth and free space.
Con Low bandwidth
Con Dropbox keeps deleting features, chasing customers away
For instance, all photo albums got deleted. It used to be very easy to share a couple og photos, now it's PAINFUL and must be done file by file.
Con Nocive development model
Takes a lot of decisions that usually damage community, from deleting features to making impossible to use with other filesystems than ext4 because they decided without a plausible reason (they said it was about xattrs, but all modern linux filesystems supports xattrs, so it's bs.)(they remove this later, but it's too late).
Con Problems when synching between Linux and Windows devices (unconfirmed)
This summer I lost thousands of files due to this problem on older projects which subsequently needed revising and had to be rebuilt as tons of the source was gone.
Con Restricted only to 3 devices for FREE accounts
Recently dropbox decreased the number of linked devices to 3, so you can't have more than 3 linked devices. This is problematic if you use Dropbox to sync between your computers.
Con Can unintentionally delete your files if you reinstall your OS without closing Dropbox
If you reinstall the operation system for your PC and you do not close Dropbox, it will delete all files.
Con Doesn't work well in mobile browsers
The functionality of the mobile version of the site is a bit limited, while new features have been added such as the ability to move lines of text, even that is limited on Android to only being functional on Chrome.
Con Offline desktop app requires Chrome
The offline desktop requires installing Google Chrome first before the WorkFlowy app can be installed. This is not good news for non-Chrome users especially users who frequently uses Firefox or Safari as their default browsers, in which Chrome app also suffers memory leak and battery issues.
Con Inconvenient interface
Notes automatically collapse, making them unreadable without user interaction. You cannot view multiple long notes at once.
Con No public API
Con Cannot use link-text
You cannot have text link to a URL. When you link to a website you have to post the full URL instead. Instead of having the name of the website or article like, Slant, you instead have to post http://slant.co
. It's especially annoying if you have a long URL that takes up a lot of space in the document.
Con No support for Right-To-Left languages
Mixed text is scrambled, and text-alignment is wrong.
Con Doesn't work on all mobile phones
Not compatible with Android OS version 4.1 and 4.2.
Con Infrequent updates and new features
WorkFlowy works well but it is hardly ever updated, in comparison to Dynalist, which works in a very similar way but has more features and is updated weekly.
Con Only supports one big text file
Although with Workflowy's focus feature this can work, you might prefer managing separate text files.
