In January we forecasted a 3% decline IT purchases in US dollars;
we now are saying its a 10.6% decline for 2009
Why the worse outlook?
Q1 and Q2 2009 cuts in tech purchases were much deeper than we
expected, due in part to deeper recessions, but also due tobusinesses in the US, the UK, and several other markets cutting
capital investment way back.
