Not much else new to report yet.... But, here are some clarifications: HTC is sending this Honeycomb Update along with the newest "Sense for Tablets" and it is supposedly tailored to the Flyers 7 inch screen.
As for the Hardware Buttons.....No, they won't light up anymore or be useable. It would be a nightmare for the UI to have dual inputs, so they are disabled in HC. In ICS, (Mature Complete Honeycomb) it is Either/Or. In other words, on older devices, if you continue to use the Hardware Buttons, you won't get/see the new Software Buttons. There is no "Workaround" that HTC could have used....and if there was, you can bet they would have likely tweaked it into their "Sense" overlay.
For Myself, while I look forward to the new overall Customization, it is the Full Magic Pen support that I look forward to the most....and the thing that sets the Flyer apart and above almost any other Tablet. This is what we were Promised. Fingers Crossed.....D
