I thought about trying the beta but isn't the beta only the freeware version? I have the pro version so I can sycn with my USB drive. I don't want to get into a situation where I'm actually losing features by trying the beta.
"Technically" (as Leo from the EverNote forum said), the beta is actually more like the paid version... But for free (trial). For non-paying customer, the beta version will probably expire after a while.
Of course, betas are always a bit more risky (although I've not experienced any thing bad with Evernote). You can't install 2.1 and 2.2 side by side. You should test it first (Image your drive, backup you database...) if your database is important to you.
How do they handle upgrades once it gets out of beta? I bought through Handango. Do they send everyone a new download link? (I guess I should be asking this over on their forums )
When you'll select help—>check for update, normally it will download the latest version. If you paid (and then probably have something written in your windows registry), it should update to the EverNote Plus 2.2 version. If not, just complain at their forum (I will if something like that happens)... They're pretty receptive (not like the gemX folks...
