Since Amazon has started selling the Touchpad for $399 and 499, both 16 gb and 32 gb have moved into the top 10 selling tablets on Amazon (right now #5 and #7 respectively)
Up until yesterday, the tablets had been at #18 and #40 (32 gb and 16 gb)
So, now we know what it takes to move the Touchpad: make it cheaper. This is good for us and good for HP. Let's hope it continues.
