I was just over at the AT&T site and for the hell of it, I checked my upgrade status. If I select a Pre Plus for a replacement, it shows a price of free with contract renewal for the Pre Plus or Pixi, and a $99.99 price for the Veer.
So, it looks like the comment about "making it right" from HP may include(or be limited to) giving people an early upgrade for EXISTING Palm owners. This may not do it for those with an original Palm Pre on Sprint, but if they offer a $200 with 2-year contract upgrade for the Pre 3 when I have only had my phone for 13 months so far, that seems reasonable.
Note that my wife has an iPhone 4 and is not yet at the 1-year mark, so it is NOT offering the "free with contract renewal", or it is limited to those with a WebOS based phone.
