The battery in my PMP is dying, and as it's not user-servicable, I'm looking to replace the whole PMP. It was an IBM freebie, so I can't just buy the same unit again (nor is its USB device ID informative). I'm after recommendations that will meet the following requirements -- they basically describe my old device. - can walk into a local store and buy it. IOW not a DIY project and not "order online from <some gizmo site>". - MUST play MP3s (yes, opus/speex/flac/tremor would be nice, but I doubt they're available in commodity hardware). - MUST have 3.5mm headphone audio out. - SHOULD charge over USB. - MUST last at least 2h playback between charges at time of purchase. SHOULD be a lot more, so that as the battery slowly dies, I don't care. Once it drops below about 40min playback between charges, it becomes useless to me. - SHOULD cost less than A$200. - SHOULD be small and light -- on the order of a couple of USB keys. - SHOULD be headless (no screen). All I need is play/pause/off, next-track, and vol-up/down buttons. If I want to know what I'm listening to, I'll bolt backannouncing into the audio stream. If I want to go to a specific track, I'll plug it into a "real" computer. SHOULD use mechanical (not touchscreen) buttons, so I can skip tracks by hitting next-track through my jacket, rather than having to open it and reach in. - MUST talk to a computer over USB mass storage (or, I guess, simply take an SD or microSD card). I should be able to plug it in, drop a bunch of MP3 files into a folder, and it should just play them. SHOULD play them in the order they hit the disk, so that - streamripper of a radio station into individual MP3s will play them back in the order recorded, so streamripper's unreliable track-edge detection becomes a non-issue; and - a simple cp -a of an album will play it back in track order (because cp will copy the tracks in lexicographic sort order). SHOULD NOT need a magical "index" file for the onboard OS to "see" tracks, as the old gen2 & 4 iPods did. (Anything that needs iTunes or similar is *right out*). MAY use a FAT filesystem. NTFS or HFS+ would actually be an inconvenience for me at present. - if onboard storage (cf. SD card), SHOULD be at least 2GB. The key words (in uppercase) are per RFC 2119. A glance at jbhifi.com turns up a A$52 Sony B-series Walkman which looks close to what I want. Does anyone have experience with it? PS: no, I don't have a cellphone, so I can't use that to play music.
