我猜楼主是说的苹果的iTouch,Version 1和Version 2的差别如下。
The v1 is 1.1.1. firmware, the oldest you can get. You don't get the mail, weather, maps, stocks and notes with it.
The v2 is the newest 1.1.3 firmware with the following features:
the five apps(maps, stocks, weather, notes and mail)
Customizable home screen ( you can hold down an icon and then you can move it. you can have up to 8 pages of apps. you can swap the icons you have in your dock)
You can make web clips ( bookmarking a website) and transform it into an app, for quick access.
