Brett Kelly ponders the switch from Evernote to Notes and the differences between the two services. While listing the main differences he remarks:
Evernote works on platforms beside OS X; if you’re all hot to trot with Notes.app and you have a Windows computer at work, Notes becomes a whole lot less usable.
This isn’t entirely accurate — Notes is available on iCloud.com (if you use an iCloud.com email account for iCloud) as well and will work in any modern day browser. A more accurate way to describe Notes’ cross-platform compatibility is that it only has native apps on OS X and iOS.
Evernote still beats Notes in nearly every comparable column; however, the new version of Notes is a huge update for those that use it regularly.
