Portable Audio Recorder (minidisc Replacement), What should I buy to replace my MD-recorder? Options

[keybie]

I've been using a Sony MiniDisc recorder for several years now, recording environmental sounds (while travelling, lectures and whatever. It's worked fine for the most part, except for the following:

• A hassle to transfer to my Mac (realtime and analog audio transfers only due to copy-protection circuitry)
• No date/time stamp
• mechanical noise from the recorder effects recordings
• low battery life (it suddenly dies on me -come to think of it, it might be time for a battery replacement after all these years though I think my batteries never lasted long before needing a recharge).

What I do like about it however is:

• Small size (handy to bring along almost anywhere)
• Line inputs in addition to mic (allows flexibility -recording from other electronic devices)
• Unconspicous (looks like an audio playback device, especially when I have my headphones plugged in). Doesn't scare people off, or being told to "stop using that thing" by various people
• Allows me to name each recording
• Good sound quality
• Removable recording media (I'm not dependant on dumping recordings over to a computer when travelling, but can replace it with a new, blank MD disc instead)

I've been out of the audio scene for a while, but it seems flash recorders (using memory cards) are the thing nowadays. That would probably solve my digital transfer issue, and most likely the time/date stamping as well (I assume these recorders have built-in clocks), but depending on recording capacity/quality I prefer the ability to have removable recording media. Then again, that might be the way it's going with memory cards getting cheaper and storing more.

So, with the good and bad experiences with my MD recorder, what would be a good replacement for it (improving on the downsides, but keeping the features I like)?
