I've been using web2py lately and like it a lot. It is a Python-based framework with a Rails-like MVC structure with JQuery and Ajax functions built in. I find it much easier to learn and use than Django. It has functions like SQLForm.smartgrid() that create a table-based interface to a database table with built-in search, sort, pagination, CRUD, and buttons to linked tables--all with a single line of code. Functions like this and more make it trivially easy to create easy-to-use front- and back-end user interfaces.

By the way, if you are a geek, you should consider one of these before you buy an iPod Shuffle; more features for less money, and it works as a USB storage device so it works perfectly well on Linux.

If you want to play Ogg audio files, I've found cheap, unbranded 2GB MP3 player/FM radio/USB stick S1MP3 combos available on Ebay will also play them. It's usually not documented in the instructions nor in the seller's online listings, but they play Ogg just fine. I've bought three of these units so far and they all did Ogg. In Linux you just mount them like any generic thumbdrive and transfer audio files to them.
