Every phone is a bit different when rooting...evo, captivate, fascinate, require different root procedures.
When the fascinate released...took a few weeks to figure out root and as time went on, got easier. Now we can root the fascinate under 5 mins. DX can do it in 30 secs.
The TB as you may know took a couple weeks to get root....they are starting to get some good stuff there.
Any new phone will have teething probs at the start. We will have ppl working on deving this phone and shouldn't take long before charge owners will enjoy the goodies I do on my fascinate.
When you choose a pro active approach ie root/rom, yes, software updates mean nothing.
