I was recently downloading something from the internet and I kept my computer running through the night so that I can complete the download. Like me, I think a lot of you guys download stuff regularly and most of the time your computer is running just for that download. So, I was thinking of some small device that has a few gigs(1 or 2) of storage and that can just run a downloader software. You could set up the downloads through your computer and then turn your computer off and start the download. Then when the download is complete, transfer the file(s) from the device to your computer. The main feature of such a device would be power saving. It can have some common ports(serial, usb, ethernet etc.) to connect to the internet. I think such a device can be built very cheaply like these popular MP3 players. And it can help save a lot of power. Power bills could be reduced and the costs recovered in a few months. So, what you guys think of this? May be it's a silly idea but that's what I think.
