Quickly reviewing what I got right and wrong 5 months before iPad was announced, in my blog post Piecing Together The Apple Tablet. I got everything right except the dimensions of things and the multi-tasking (which comes later). [2025 Editor's Note: This was not what most people were expecting from the iPad at the time]

Right:
100% multi-touch.

Right:
Glass and aluminum.

Wrong:
The virtual keyboard will be full size.
No, it will be kinda-sorta near full size.

8.25" x 11" dimensions.
It will be 7.5" by 9.5".

The bezel will be 0.25".
It is about 1". In order to hold it properly.

Resolution 1600 x 1200.
It will be 1024 x 768.

Right:
Thickness of an iPhone.

Right:
Non-removable battery.

Right:
It will run an OS far closer to iPhone OS than to OS X Leopard.

Right:
It will use the App Store exclusively.

Right:
It won't be a "full purpose computer."

Right:
The Apple Tablet will be for stuff like surfing the web, email, taking notes, calendar, YouTube, music, games.

Right:
The Apple Tablet won't be very powerful, like a typical laptop.

Right:
The Apple Tablet will only have a headphone jack and iPod connector. Nothing else.

Right:
No moving parts. No Stylus.

Right:
The app for music will be called "iPod", it won't be "iTunes" like on Mac OS X.

Right:
It still needs a full purpose computer around to sync to.

Right:
The Apple Tablet will be the first non-mobile device for the masses that will be as easy to use as an iPhone.

Right:
Apple will equip it with a full complement of completely multi-touch optimized applications.

Wrong:
Multi-tasking.

Right:
One app on screen at any given time. No Windows. No OS X menu bar.

Right:
Built-in Wi-Fi and Bluetooth.

Right:
It might have 3G capabilities.

Right:
Not a phone.

Right:
There's always a camera in your pocket (the iPhone) for a better experience than lifting the tablet up to take a photo.

Wrong, Wrong, Wrong:
It has to support Flash.
