GOODWILL :) I did an almost complete research to compare note-taking softwares: Devonthink pro(DTP), yojimbo, SOHO note, Mori etc. I finally tested DTP, SOHO note and Yojimbo. Based my experience, all of them have both pros and cons. I finally choose SOHO note due to its rich of features, particully for two unique features: quicknote and flashnote. The early version of SOHO note has two major problems: instability (buggy) and slowness. But after it upgrade to 6.2 and now the 6.3, the application is quite stable now. And the speed is much better than the earlier version (but still slower than DTP). I also notice that if you want to upgrade from earlier version, the best way is completely uninstall the earlier verion and install the latest version from the ground.
(Version 6.3)
