Show HN: (pre-beta SaaS) "Get organized, get Headspace"

I am a software engineer working alone on a passion project, a website that helps you stay organized easily and efficiently.

Headspace.io is a webmail, notepad, task list and calendar, all rolled into on. The basic premise is that any data in Headspace can be "tagged" and then all relevant information for a particular tag can be displayed in one screen.

This is a pre-beta build and I'm hoping to get some early feedback from the wise and generous HN folks. Would you pay a small monthly fee ($5 maybe) for a service like this?
