So....... After stumbling upon, & reading through this thread in it's entirety, I decided to take RomeoSidVicious' advice & STOP using TaskManager, just to see if it would fix some issues w/ my Hero. I was having issues w/ HTC Sense rebooting, sluggish performance, very slow boot ups, poor battery life, etc. It's been 3 days now & I can honestly say W O W!!!!
What a difference, battery life is 2-3 times what it was, NO reboots, phone is "zippy".
I have no, read NO experience with anything Linux based, & was operating under the "kill 'em all" mindset from my MS Windows PC upbringing. Everything I read prior to getting my Hero said to make sure you get & use a task manager, so I did, I tried 3, & all had similar issues. I have since uninstalled all but the Task Manager included with Astro File Manager, & have not killed a single task in 3 days! I am now a Reformed Killer, & vow to let Android do it's job as an OS. Thank you so much Romeo, you are the Linux GOD!!!! +2 for the "grok"
