what are the chances that the 3g will be radically different? The 2g is radically different from the 1g so maybe not much will happen except for a hard drive increase.
Aside from the jump from the original iPod 1st Gen to 2nd Gen, every new generation of every iPod has included major upgrades/changes. Check it out
here.
On the iPod touch 3rd Gen, I think we'll see:
-Copy/Paste (3.0 Software, Already confirmed)
-Bluetooth compatibility (3.0 Software, Already confirmed)
-A slightly larger screen. Perhaps a full screen, with the home button moved to the side above the volume rocker.
-GPS
Aside from those features, the only other thing I would like to see on the next generation touch is a camera. I know that thousands of people have said that there's no way the touch will ever have a camera, but, as many others have already said, didn't thousands of people say there would never be a touch-screen iPod?
The reason I think we may see a camera on a future generation of the touch is because it fits in with Apple's slogan for the touch: "The Funnest iPod Ever." Music is fun. Videos are fun. Using the internet is fun. YouTube is fun. Games are fun. Other Apps are fun. Cameras are fun. So it may not come in the 3rd generation, but I think we'll see a camera on the touch at some point.
All that said, I'm still trying to decide whether I should ask for a 2nd Gen touch for my birthday (in April) or just save up and wait for the 3rd Gen to come out in September.
