Two things I want but am too lazy/ignorant to build myself:

One: I want instant translations of words I do not understand in texts I am reading. I want to point my phonecam at the text, take a picture of the word and send it to a service that does OCR on the image and returns the dictionary entry to my phone. And it should take 3 seconds.

Two: My apartment building’s laundry rooms have just been upgraded. Access to the rooms is now computer controlled: You have to wave a card at a machine at the door and then navigate a computer menu to the time you want to book the rooms for. All good and well, except that the laundry room is down a flight of stairs and at the other side of a courtyard, temperature -10°C. Since this building has pervasive 10Mbps piped into every apartment, why can’t we just book over the internet? An outside company could provide this service for many computerized laundry rooms. Not only could you book ahead, you could ask for email reminders, or have it alert you when the laundry room is free (my favorite feature), or have your laundry time show up in your iCal, or find out about broken machines and list lost/found items on a laundry bulletin board. I’m the kind of person who cannot plan ahead, so I lug my laundry all the way there only to find the rooms used. This service would be a real help.
