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.
Pro Up to 18GB of free storage space
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.

Pro Linux support
Dropbox offers native Linux support, integrates with Nautilus file manager.
Pro Reliable
Pro Desktop client has no file size limit
As long as you have enough storage available, you can upload files of any size using Dropbox desktop client.
Pro Folders can be downloaded compressed to save bandwidth
To save bandwidth and download speed you can choose to compress a folder into a zip archive for download.
Pro Adjustable bandwidth use
To not slow down the network or save traffic you can limit the upload and download speeds of Dropbox.
Pro Lots of addons and integrations
There are official and third-party Dropbox add-ons that extend the functionality of the service and add ease of use of existing features.
Additionally, Dropbox can be integrated with existing applications to bring its functionality to other apps.
Pro 30-day version control
Dropbox keeps deleted and earlier versions of files for a month.

You get extra free space for you and your friend if they sign up.
Pro Fast sync speed
Pro Web and mobile versions available

Pro Notes can be shared and collaborated on in real-time
MindMeister allows sharing maps with an unlimited number of collaborators so it's possible to take notes and brainstorm together. Mind maps can be shared by inviting people either directly via email or by sending them a link to the map. Even people without a MindMeister account can access the maps and even edit them.
Pro Comments and votes
Users can create polls and have collaborators vote individual topics up or down, or comment on them.
Pro Various layouts
User can switch between classical mind map layout, a layout where all topics are aligned on the left or the right, and org chart layout.
Pro Clear overview without losing any details
The mind mapping format provides with a clear overview of connections, hierarchies and relationships of notes. At the same time, it's possible to add more detailed notes, links, pictures and even whole files to the keywords, so that no important information gets lost.
Pro One node can have marks, emoticons and comments
Pro Adding a Table or Matrix
Xmind is one of the few mind maps that allows you to add a table or matrix to your mind map. Very useful when you have content that works better in a table.
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 No good offline mode
You can only work completely offline when using an iOS or Android device. For your browser there's only a clumsy 'offline mode' available. If you didn't hit the switch before you have the need for working offline (for instance: in a meeting, at a customer's location, in a plane, etc.) than your out of luck... no tool for note taking. Especially with all those HTML5-capable browsers and the Chrome App store (including Desktop apps), this limits the usage of this commercial product.
Con Expensive compared to the competition
A basic monthly subscription ($92 USD) gives you no more than XMind FREE except PDF exporting. XMind paid with PDF export is $79. $20 less for lifetime use of an app with more features as of writing.
Con Free option limited to 3 mind maps
A free XMind app/online account or MindMup account both provide unlimited mind maps.
Con MindMeister has very poor Evernote integration
Evernote is the number one 'store-everything-archive' when it comes to unstructured data or information. MindMeister markets there Evernote integration as a very cool feature. But this integration is very basic and buggy: only the last 50 (?) notes from Evernote's default notebook are shown in the list, and it takes about 30 seconds to one full minute to generate that list. After that it takes about the same amount of time to add a copy of the selected note as an attachment to a topic. MindMeister support is well aware of this poor implementation, but doesn't put any effort in fixing it.
Con Very basic
Con The interface has only very basic features
For example, it lacks the possibility to define a long text under the node title showing it in a permanent way. The software is 1000 less powerful than Microsoft Visio. Meanwhile it should just be more specific.
