Just a comment really. Having happily used Rockbox on my Toshiba F40 for some weeks, bought Mrs seani a Sansa E280 from Costco, and Rockboxed it before she could become accustomed to the original firmware.
Worked first time and she's now happily listening to music and playing too much Frozen Bubble (or whatever it's called). The recording interface is a bit confusing (doesn't seem to save anything) but I haven't digested that section of the E280 manual properly.
Excellent stuff.
Incidentally, I originally composed this using "RB" for Rockbox, "OF" for original firmware and "F40" instead of "Toshiba F40". Are these abbreviations generally thought acceptable ("RB" and "OF" particularly) with respect to posting guidelines? How about the likes of WRT and AFAIK etc?
