As a tablet, the iPad 2 is already an excellent product. While many are hoping for higher resolution screens and quad core processors, this are some of what I hope Apple gives us this March.
1. A keyboard dock, like the Asus Eee Pad Transformer Prime, but ad a nice sturdy kickstand to put the keyboard at a nice typing angle. Apple has a nice word processor, this will make it even more productive.
2. An external hard drive which can plug into the keyboard dock.
3. A slice battery that can be mounted under the keyboard dock for 20 hour battery life.
4. A stylus. Plenty of nice drawing apps in the App Store.
This would make the iPad the ultimate post PC tool. A tablet, when desired. A laptop when needed. An intercontinental device for frequent flyers. A serioues photo editing tool for all.
