The use of technology in this match:
Pietersen "caught down the legside" - Technology inconclusive (we didn't see the angle that usually sorts these dismissals out ie. the view from behind)
Gillespie LBW - Technology inconclusive (Television looked dubious, Hawkeye said out)
Bell dismissal - Technology inconclusive (TV angle from behind gave some suggestion of a nick, Snickometer said zilch)
Pietersen dismissal - Technology says NOT OUT
Kasparowicz dismissal - Technology inconclusive (Definitely hit his glove off the bat but quite possibly hit the shoulder of the bat first)
Seems like a recipe for little more than even slower over-rates to me
