iPhone as music server remote control

Dshapiro turned me on to something like this. My understanding was you could buy a itouch {$299} from appla and install nettunes and use it as a remote. Are these other software programs better than nettunes? I have no experience.
I want to buy a mac mini and have a wireless remote controller to run itunes from my chair. What would be the smoothest way to do this?

Sidssp,
Your first link looks just what i am talking about. Has anyone seen the itouches? Boy, they are georgeous!

Would it matter which mac mini you bought if you were going to hook up external hard drives? I might pick one up cheap{ and no tax} on ebay. You don't need bluetooth or anything special to use the itouch do you?

Streetdaddy,
yes you need bluetooth for the macmini/itouch connection. iTouch as a remote for playback works BUT getting the music on the server, manipulating the music, iTunes, etc requires a monitor and keyboard. A cheaper version of the same thing would be to buy an old Palm Pilot and get Salling Clicker software.

My solution to this will likely be iTouch for remote (because I can use it elsewhere too), and unplugging the MacMini from the stereo and plugging it in elsewhere to deal with the rest when the need arises (either that or grab one of those great-looking new Appple wireless keyboards and and a DVI/HDMI adaptor and plug it into the TV.

Tbone,
The palm is definately not 1/2 as cool as the itouch. The itouch looks sooo much better than an old crappy palm pilot.

I geuss i'm a litlle confused. Say, if you want to play your playlists, you can't just grab your itouch and control itunes? You need a seperate keyboard monitor?

What is the itouch for then? Also, what else can you do with the itouch?
