I love Jott.
Sign up for a free account, give it your email address, and you can call an 800-number anytime, talk into the phone, and have your words instantly converted to text and emailed back to you.
(You can have it sent other places as well, of course — texted to phone numbers, emailed to other addresses, even posted to Twitter or whatever — but I use it exclusively for notes-to-self.)
I know, I know, this feels like the kind of thing that sounds great in theory but is somehow fatally flawed in practice. In fact it’s great in practice, too — Jott’s voice-recognition software is uncanny.
Highly recommended. Will make you feel like you’re living a couple of years in the future.
