Among them: missing Ruby certificate, issues with handling spaces in the paths under Windows, selecting between gems mysql and mysql2 and finding version and platform of mysql2 which works with Windows, gem nokogiri can be built only as native component.

There are a lot of services intended to solve this task. I will describe below criteria which I used to select service for my usage. I will also describe my experience of testing and using some of that services.

I will touch Google Docs, Apple Pages as a part of iWork for iCloud, Evernote, Simplenote, Microsoft Word Online as a part of Office Online .

Apple also provides Notes application with synchronization support for free. But I will not describe it here because it is very simple and lack a lot of basic features.

Despite described products may evolve and change fast the described features below can be used during the choice in the future even if product changed significantly. Article could be helpful for you even if you consider a service not mention in this post. It can be used as a list of criteria.
