Most likely a faster processor (1GHz), a 5MP camera with 720p HD video capabilites, as well as the new iOS 4.
The iPod touch has much more features.
YES by far, the ipod touch has waaaaaaay more features and its touch screen with built in speakers
Once you pay for the iPod Touch, you are done paying for it. You do not need to pay for the extra features.

The creation of the iPhone led to the development of the iPod Touch. The iPod Touch was meant to be a non-phone alternative for a touch screen iPod, and just a next line of iPod.
The iPod Touch was created to fill the market void for people who wanted the features of an iPhone without being tied to a contract or necessarily wanting the features of a phone. With the increased capacity of the iPod Touch over the iPhone (32gig for an iPod Touch, 16gig for an iPhone), it has also come to fill the market voice for people who want both the features of the iPhone and the larger storage capacity of the iPod Touch.
Ipod touch is bigger (in physcial size), is newer so it has more features, and it is just one big touch screen.
ipod touch 4 has 2 cameras, retina display, ios 4.0, multitasking etcect
The ipod touch 4th gen is the only ipod touch to have a built in camera, microphone and gyroscope (for better motion sensing)
An iPhone is an iPod Touch (iTouch) with the phone and camera. Thus, an iPhone is already an iPod touch with more features.
The difference btw the iphone and the ipod touch is that the ipod touch doesn't have the phone or the camera. Personally, i would get the iphone 3g because of the phone and its cheaper than the ipod touch with more features. but now the new ipod touch 4g has a camera which the iphone has the same
