above backs that statement up as you can clearly see it running smoothly on the HTC Tilt.
Apparently, they’ve managed to get data, audio, GPS, Flash, Market, Gmail and all the HTC apps & widgets to work so far. SMS and the camera are also partially working. “From first boot up, it goes right to the HTC setup. After that, it goes straight into the Sense UI. There’s a bit of lag initially, but after everything gets settled down, it becomes quite usable.”
Zenulator has been working on two different builds, the full Hero UI and one that he calls BackInBlack or the “minimal build.” The latter is a stripped down version that is a lot faster while still utilizing Sense UI and HTC widgets. Currently he’s concentrating on the minimal build because of its speed, but he will have the full build out shortly. So far it is reported that it works well on several devices. Check out the XDA-developer’s thread to see the lively discussion or to attempt to port it to your device.
