I have several iPods ...
30GB - white - music only
80GB - piano black - video, photo, music
2GB - silver - nano - photo, music
16GB - touch

The Touch is freaking awesome. It has a very usable interface and the WiFi + Safari or YouTube works flawlessly. If I have to check email, I don't even bother with my PC anymore. The Touch can connect to the internet 5 seconds after I turn it on.
