Clearly the far more important factor for tech is the relative strength of the economy. It trumps the dollar situation. But if the dollar improves, it does take the bloom off the rose for some of the sales numbers that companies have reported.
Normally I'd say it's just a number but I think it's relatively important this time around. If we break through 11,000, it might be indicative of a general feeling that the economic expansion is more broadly based.
There seems to be a wide disconnect between the headline growth numbers and individual perception about the relative health of the economy.
