A few comments
A) It's not 250,000 Touchpad's that are left, that was just the remaining inventory at Best Buy. The IT channel has thousands that haven't sold in major distributors and tier 1 and 2 retailers.
B.) HP couldn't put Honeycomb on the Touchpad. When Google created Honeycomb they started making restrictions on the devices that could run it. Ex. To run Honeycomb the Tablet must at least be 10 inches, have a dual core processor and HAVE A FRONT FACING A REAR FACING CAMERA. The Touchpad only has front facing camera so it doesn't meat Google's standards and thus the transition could never be official.
C.) Android 2.3 on a 10" tab is the most frustrating, glitchy POS on the planet. Certain apps don't resize, constant glitches, not smooth flowing, etc.
D.) Who cares if HP continues to put out updates, the WebOS app store sucks and it's only going to get worse now that HP isn't behind it.
