I use the Palm Zire 71, and have used Palm for about 7 years. I couldn't function without it. I find that 16mb is plenty, especially considering you can use the memory chips for storage of music files and photos. I use the digicam in spontaneous situations and more than once it has saved me from missing a "moment". It also has software which lets you play MP3's, and play mini movies. All in all, I am extremely satisfied with this unit. It may be the best one I have used yet.
