So far so good, here. Updated from No_Twiz (Pre-Twix) to Warheads this morning, updated the kernel, and so far the battery's fine (75% left, after using SkyFire to watch videos for an hour, GPS and WiFi on). And that's without letting it drain after updating.
The phone appears to be sleeping properly, though I do still need to toggle WiFi off/on or manually reconnect after waking up. Home++ seems to be working fine (no reloading of the app drawer, battery life is, as I said, fine, and sleep works)
The ROM seems quite fast, GPS and the gyro seem to be a bit more "crisp" at this point.
Not sure I actually would need the Hybrid at this point... I'll probably hold on to this one 'til 2.1. (As you can tell by me skipping Twix and Dots, I have no issues with "holding out" ;->)
