Remember the milk is a simple web based todo list that is quite powerful. The power doesn’t lie in the service itself, but rather in how it interacts with other services. We all hate having to go to ten different apps to do one thing. That’s one of the reasons an app like Outlook is so popular. You have a single application that handles you mail, contacts, appointments, todo etc.

With Web 2.0 trying to find it’s place in the world this is one of the challenges it faces. We’ve already seen many of these issues addressed and data portability remains a big topic of conversation. But I digress.

Remember the milk (RTM) does this so well. Remember the milk is just a simple todo list. There are many out there that have more features, but it’s not features I want. I want to open my Gmail and see the ads removed and my todo list instead.

I want to open up Google calendar to check my appointments, and I want to see my todo list there.

When I open firefox, my default page is iGoogle. I want to see my todo list there too.

When I’m standing in shops wondering what I was supposed to buy, I want to whip out my iPhone and check that I haven’t forgotten anything.

If like me, you’ve managed to break your iPhone and you have to resort to using a black berry again, you might want your todo list there.

And to top it all off. If you’re a twitter user, you can even add items via twitter, and get some reminders.

They also provide you with a unique email address that automatically turns the email into a todo item. So you could use a service like sendible to email you a todo item at some point in the future. Random, I know.

I’d give this 10/10. I have finally found a todo solution that might actually work for me.
