Well if you are among the many out there that have been waiting for the iPad to finally land for pre-order, get that credit card out. The Apple Store has been down for a few hours now; meaning new products were being added.
The store is back up right now and pre-orders for the iPad are being taken. If you are planning to buy any version of the iPad, they can all be pre-ordered today.
The WiFi models are listed as shipping on April 3 with all the 3G versions showing a late April ship date. We aren't sure if the iPad will be limited at launch, so if you want to be sure to get one head over to the Apple Store now. You can also pre-order official accessories along with the iPad.
