I'm really starting to dislike my Evernote desktop client. It's so slow to start up and it hangs all the time that it makes me not want to have it open sometimes. Don't get me wrong, I love the service, but Evernote really needs to improve their desktop client. They rolled out an update last month that promised to be faster but so far I haven't seen much improvement.
While my normal monthly usage is still well below the 40MB limit, I did come dangerously close to that last month when I decided to add a year's worth of PDFs from Trendwatching's monthly briefings to my Evernote archive. To date I have 371 notes and ~60 MB of data.
I think I might also be dangerously close to becoming a Level IV digital hoarder. :)
