I just became a member of MP3tunes. I love the service. Basically, MP3tunes is like a Flickr for songs. With MP3tunes you post your songs on the internet and you stream them back when you want to listen to them. Why would you want to do this? Because you, like me, may have many more songs than memory in your devices. In my case it all started with the Nokia 770 tablet and its 512MB of memory vs my 33GB song collection.
Now the main problem of MP3tunes is something that the FON Liberator will solve and that is the cumbersome nature of massive music uploads. Massive music uploads or downloads, say uploading my 33gb music collection to MP3tunes for example, take forever. Say two full days. And who wants to be stuck to a connection with a laptop for 2 days? So the FON Liberator basically liberates you from tying up your laptop in this process. With the FON Liberator, which should be available at FON by January for around $85, you will basically stick your external hard drive or iPod to the Liberator (a FON social router who doubles up as a Linux mini computer WiFi media server) and tell the Liberator over the internet to send all your songs to MP3tunes, or your videos to You Tube, or manage your Torrents or any large upload and download and you will not need to be glued to your laptop.
We are now developing a cool web interface for massive uploaders/downloaders to decide what type of files and where they would like to upload/download. I see 2007 as the year in which the internet migrated to the pocket, WiFi became ubiquitous and devices will start using web storage in a massive way. What is now a geeky thing with less popular devices like the N770 will become massively deployed when handset makers launch most phones with WiFi (Nokia is already making around a million a month of these).
