I wish there was something I could hook up to my electronic life (calendars, search engines, knowledge stores, bug tracking, etc) and send IMs to from all devices. Like Siri, but more useful and more connected. A general, all around AI instead of a glorified Google search with speech.

Example commands I wish I could do (some would require me hosting a server to communicate with my home, but I'm okay with this):

"Lock my doors." "I'm going home." (Notify people, set AC, bring up a map, etc.) "What's the weather tonight?" "Write 'happy birthday!' on my friends' Facebook walls each time it's their birthday." "Ask my girlfriend what's for dinner when she gets on Skype." ...and so on...

That said, I'm super excited about this and would love to see Maluuba's work accessible on all devices so I can just IM the service instead of using a phone when I'm at home.
