Hi, thanks for your response... I primarily use my computer for photo editing work, and although it is not blazing fast, I can edit in Lightroom with little lag. With that said, Evernote takes longer to load that Lightroom, which is notoriously resource hungry. The internet where I live is not super fast like you might see in the States or Europe, but it should be fast enough to support the data update process of EN without a problem.
I do not load Evernote on my PC everyday, so I'm sure there are some files that need to be sync'd but again, it's usually minimal at best... I don't use EN as others might... for me EN is more of a filing cabinet for my life, a few web clips, and not much more than that.
