Pros
Pro Web and mobile versions available
There is no installation of the software required. MindMeister runs in any standard web browser as well as on iPad, iPhone, and Android devices.
Pro Notes can be shared and collaborated on in real-time
MindMeister permits sharing maps with an unlimited number of collaborators, making it possible to take notes and brainstorm together, much like most online Evernote alternatives. Mindmaps 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 edit them.
Pro Clear overview without losing any details
The mindmapping format provides 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. This is a wholly original design when compared as an Evernote alternative, which may appeal to those who think Evernote is lacking in this area.
Cons
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 their Evernote integration as a very cool feature. However, 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 Poor 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, during a meeting, at a customer's location, or in a plane, etc.) then you're out of luck - there's 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.
