I don't mind the 200MB limit most of the time, but I do find it problematic every now and then. I wouldn't expect Evernote to raise it substantially though. But I would like the ability to pay Evernote extra for the occasional notes that need to bust that limit - most have pictures, video, or particularly large PDFs in them. Compressing the files into a ZIP before attaching to the note rarely helps since most of those formats are compressed, to begin with.
The only possible workaround I have is to insert into the note a link to the file on Dropbox. But that defeats the entire purpose of having the content in Evernote in the first place.
