Are you asking us to chime in as to our thoughts on the iTransport? If so...
2 words - Ergonomically inept. Its remote is practically worthless, especially when compared to another product I'll name in a few minutes. It literally was an afterthought according to one reviewer who said they initially didn't have one, then had to push back its release because Apple required one.
Due to its remote's worthlessness, you have to control the iPod from the iPod itself. That's ok if its right next to you. But the angle of the iPod and how it sits make using the controls a bit risky IMO. I thought I was going to knock the iPod off and/or break the connector.
It would have been a great product if it had a functional remote like the SB Duet's or was controllable from an iPod Touch/iPhone. The Touch makes a killer remote. Another potential improvement could have been an on-screen display for the controls, like the Apple TV.
For less money, you're better off with an Apple TV IMO. Its far easier to control - on TV and/or iPhone/touch, has a digital out, and does a bunch more things, and costs less. And you don't need an iPod. The only way it loses out is that friends can't connect their iPods to it. But I guess they could bring over their Apple TVs

I'm not bashing it for the sake of bashing it. Its a great idea on paper, but fails miserably in application IMO. The people who'll be happy with it are probably those who don't know better or the type who are anti-remote. (I could never figure out why people want stuff that has no remote capabilities, but that's another conversation). I have no interest in whats on my friends' iPods. Not because the music, but because they compress the hell out of their music. If I want to play my friends' iPods on my system, I'll buy a cheap mini to RCA cable. There's no way a compressed file will sound good.
Just my opinions. I'm sure others will disagree. I've read a bunch of reviews on the iTransport, and none of them touched on controlling it. I'm not saying it sounds bad, I just couldn't live with it due to everything else. Its a good thing I tried it at a shop rather than order it and have to send it back.
