If you’re in the market for a cheap 3G tablet, at&t just slashed the price of the first generation iPad. The 64 GB iPad 3G now costs $529, a $300 discount when compared to the price of the device when launched in April 2010, and $130 cheaper than what Apple currently charges for the same model in a refurbished state. Similarly, other models are enjoying discounts as well. The 16 GB iPad 3G now costs $429, a $200 discount when compared to the cost of the device earlier this year. The 32 GB model is currently out of stock. If you decide to sign up for the 2 GB per month data plan, note that the first month will be free of charge – an additional $30 discount.
