The Logitech K750 is already solar and wireless and I've been using them for nearly a decade.

Might yield interesting results in getting higher numbers of young people voting in future elections. That's a win for democracy, I'd say.

When you buy a physical disk, you don't own that content either, so I can't say I'm not surprised by this. If you did own the content, and if your disk was later damaged, you'd be able to get another copy of it for free or for a minimal price for materials. Or if you were to upgrade equipment--say DVD to BlueRay-- and if you owned the content, you would get the next encoding of that data for free. None of that happens today, so the delivery media doesn't really seem to matter to me. The movie studios license the content to Amazon, who it turn licenses it to you at a higher cost.

I'm a recent freelance web developer myself, and have found that time management is a big challenge. Not only is the spreadsheet method cumbersome, but it doesn't allow for much transparency with clients.

My solution? Write my own time keeping software.

I've been developing a web-based application that works much like a punch clock. I choose the project I'm working on and click a start button. When I'm done with that project, I can click the stop button and enter some brief work notes. In addition to this basic stuff, it has back end reporting so I can see who owes me money, view an overview of how much I've been working on a monthly basis, and more.

I've also created a client front-end where my clients can login and see what I've been working on, and can see how much time I've spent on various tasks. Additionally, they can see what they owe me for the work and can login and pay me via credit card (through paypal for now, but that may change depending on pricing).

So far, it's working great for me and my clients. I'm still finishing some of the coding of some new features, but figured I should get some beta testers in soon...so if you (or anybody else, really) would like to give it a go, shoot me an email at noyler@gmail.com and I'll demo it for you. After I feel it's a solid product, I figured I could offer it as a service for any freelancer on the web and charge something small for its use...like $5/month or $50/year.

Best of luck to you!
