Thumbs up for Rockbox on Sansa

I have a small (iPod nano-sized) Sandisk Sansa E200 player, which runs Rockbox fantastically (everything works, its battery life is much better with Rockbox, and it supports SDHC rather than just SD cards).

As far as I understand it, Sandisk hasn't exactly been friendly to Rockbox (they haven't gone out of their way to make docs available) but they haven't been intentionally obstructive in most cases (most devices' firmware is comparatively easy to replace). And their hardware offers a lot: mine is based on the same PortalPlayer ARM-based SoC as an early iPod Nano, but offers FM recording, external card slot, and microphone... none of which the first couple generations of the Nano offered. And I got it for $30 and added an 8gb SDHC card for $10.

I now have an Android phone, but for a lot of cases the Sansa is far more convenient. Its interface is more responsive, never crashes, and is easier to use while running or working out. It's much lighter-weight too... a full-size smartphone feels like a clunky, bouncy brick in my pocket by comparison.
