Apple began accepting pre-orders yesterday for both Wi-Fi and 3G enabled iPads, each available with 16GB, 32GB, and 64GB and free shipping. The Wi-Fi versions are reported to ship on April 3rd, while the 3G devices will ship in late April.

CNN Money provided the statistics on the AAPL Sanity board’s research:

• An estimated 119,987 iPads were sold
• Customers chose the Wi-Fi model over the 3G model by around two to one
• The 16GB, 32GB, and 64GB versions sold fairly equally

The iPad does not come with iBookstore app, but it is a free download. Interestingly, Barnes & Noble announced that they will soon offer their own app for the iPad – a wise move, as not all eReader fans will prefer the nook to Apple’s device. Barnes and Noble posted on their blog Thursday that this is part of their promise to provide consumers with “any book, any time, anywhere.”
