Here are some sites and services I started using in 2008 that I highly recommend:

• Jott – a great Voice to Text web app that handles short voice mails reminders, and much more.
• YouMail – a great (web enabled) replacement for your cell phone voice mail.

• Remember The Milk – to call this the best task management system on the web is a bit of an understatement.
• PingMe – kinda like hyperactive webified post-it notes… the kind the can send you a text message at just the right time :)
