I use DEVONthink too for the same reason. The only thing DEVONthink lacks is cross-platform support. It's a pity that it's not available on Linux or Android.
1. Evernote has dual-language OCR of PDFs and images (and a few others crappy formats that normally shouldn't be used like .docx, .xlsx, etc). That's a great idea. DevonThink doesn't even have Japanese support (their licensed OCR only supports Western languages).
2. Uh... OK god dammit that is really the only feature that keeps me using Evernote's horrid apps. Shit.
