MP3 Player Dilemna - iRiver H120 or 4th Gen 20GB iPod

[TundraTRX]

I'm currently looking at getting a hard drive MP3 player. I have been using the MP3 player on my Tapwave Zodiac and the third party program Pocket Tunes, but having only 256MB of 192Kbps and VBR MP3s is limiting. I want to carry more music with me, and I've narrowed my choice down to two different models. It is currently between the 4th generation 20GB iPod and the iRiver H120. Both have about 12-14 hour battery life, 20GB hard drive, and a relatively pocketable size. I used to own a Nomad Jukebox Zen 20GB, but one reason why I got rid of it was its size. My requirements are at least 20GB size (I currently have about 8GB of MP3s, and plan on expanding that very soon), more than 10 hours of battery life, and a pocket friendly size.

I have many questions about both models, and I hope someone(s) can help me out. I like the iRiver H120 for it's "openness," meaning lack of Digital Rights Management, and choice of software. My only concern is that there is no preloaded software with it. Can it easily be used with most 3rd party programs with no to little problems? I currently use Windows Media Player 8.0, and has anyone used the H120 with it? Has anyone had any major problems with the H120? I've heard reports with playback problems with low bit-rate MP3s.

As for my second choice is the 4th gen 20GB iPod. I love its design, and have had a chance to hold it. It is nice, has an awesome selection of aftermarket solutions such as car mounting kits, and other items. This is one of the big pluses the iPod has in my eyes is its sheer support by the third party market. One of my concerns about it is its Digital Rights Management (meaning you are locked to having the MP3s on the player, and the original computer. No other players or computers can share) control scheme. Has anyone run into limitations or problems with DRM on the iPod? As for iTunes on Windows, is it as easy to use as Windows Media Player to create playlists and add music to the player? Has anyone tried the Red Chair Software program Anapod with their iPod? Isn't there also a wireless RF remote for the iPod? I'd like to mount it to my steering wheel if possible.

Any help or answers to my questions would be greatly appreciated. I'm having a hard time finding enough information to make an educated decision as to which one I'm going to get. Also, has anyone come up with an easy-to-do integrated system for a MP3 player in a Toyota Tundra? What I mean is a simple plug & play solution for the Toyota Tundra like dropping the player into a cradle, or plugging it into a single cable without a mess of wires? Again, thanks for any help.
