I myself migrated to simplenote. It's more lightweight and text-only, but I can live with that. iPhone client is quite decent and for Windows there is ResophNotes, or one can just use the online version. Everything is stored in text files, which is another advantage.
As a Premium subscriber to EverNote, this news about a very bad flash card app indicates to me that they aren't serious about improving their core product and instead want to capitalize on the brand with gimmicky spinoffs.
Basically I just lost a lot of confidence in the EverNote brand.
I'm still using Evernote for collecting receipts, though. The combination of some smart Gmail filters (Amazon/iTunes/Steam/etc receipts all auto-forward to my Evernote email address) and the automatic PDF OCR (I've got a document feeder scanner) still make it simpler than anything else for that. I reference my receipts so rarely that I can put up with the painful UI once every few months.
