Ok, long time lurker but it's time for some feedback. I rooted awhile back to see what the hype was all about. Actually no big deal with the exception of being able to try lots of Roms.
Don't know what I was expecting to see but no "wow". Settled on Evil Eris V3 and really like it for the sense factor, slight increase in snappiness with the OC @ 710 and the ability to run a wireless tether.
2.2 Kaos Froyo v28 comes around and I flash and guess what... I went back to the EE Rom because I really like the sense overlay. I missed my calendar, phone contact linking, cool weather widget (actually HTC has the best widegets imo) and everything else.
Bottom line for me is that although I love the Android OS it's really the Android with Sense overlay that I really enjoy. When The Eris first came out I chose that over the moto droid for a few reasons. One being the size and the other was the layout. As someone that was new to Android and smartphones in general I didn't have any experience comparing, didn't know what I liked because I didn't know what there was out there.
Now that I've seen what 2.2 has (no sense) I think I'll wait before anymore flashing. Out of all the Roms I've flashed the ones with sense are the one's I keep coming back to.
This post was not to piss anyone off (mines better than yours) but was just to provide feedback from my experiences.
