According to Apple’s site, you can pre-order your iPad for delivery/pickup (at store) on April 3 or late April depending on whether you want Wi-Fi or 3G.  Prices start at $499 for 16GB Wi-Fi to top of the line 64GB (Wi-Fi and 3G).  You get free shipping and there’s a pre-order limit of two per customer.

To accessorize your iPad, here are some items that might interest you:

• iPad Keyboard Dock ($69) full-size keyboard, charging dock, and includes rear dock connector port and an audio line out port
  
• iPad Dock ($29) for docking and charging; includes rear dock connector port and an audio line out port

• iPad Doc Connector to VGA Adapter ($29) for connecting to other devices (e.g. TV, projector) for watching slideshows and movies

Other options include:

• Data plan (no contract) for the 3G starting at $14.99 for 250MB/month or $29.99 for unlimited through AT&T.
  
• MobileMe Membership internet service at $69 for single user and $119 for family.
  
• AppleCare Protection Plan at $99 which gets you hardware and software coverage and support for two years.

The total price of ownership adds up for this latest Apple device and Apple even offers a financing plan in case you haven’t saved up.  At minimum, for the price of the device, I would expect a few accessories (e.g. cover/case or charger) included as part of a package.  Until users get their hands on the device, the jury is still out on the whether the  iPad is a Kindle killer or just another expensive e-reader.
