Apple has reduced $100 on all iPad models on sale in US. Now listed under Clearance on the Apple Online Store, the iPad models can’t get any cheaper. So if you don’t want to wait till March 11th or feel good about the iPad 1st Gen itself, go ahead and grab the 16GB WiFi @ $399 (going up to $729 for 64GB WiFi+3G).
PS: Apple also has refurbished iPad 16GB WiFi starting at $349!
Via Apple Store
Update: Seems like the UK store is also down from £429 to £399!
