While I totally agree with what has been said here..I question if you have spent any time in the newb rezz areas in the last two years. Veteran residents do indeed harass newb residents into using a TPV. They make up any number of creative descriptions of the LL viewer to get the new people to drop v2/v3 within mintues of joining SL. Now, not all new residents fall for it and not all newb rez areas have this problem 24/7, but it occurs enough that you can find the problem.
I personally started on v2 and I loved it, I will still use v2 over any of the v1 style TPVs. BUT as soon as Firestorm came out for download in any form, I got it and I will swear by it. It is hands down better than v2.
But I enjoyed the fact that I had the decision to choose whichever viewer I wanted to use, a freedom I still enoy at this moment. If in fact LL decides to push out the TPVs, they will lose me and my SL businesses.
