Are you speculating or investing? What's your time horizon?
I expect a two-week rally in the S&P500 to about 850 over the next two weeks (an 8% rise), followed by a significant decline below current levels. The major trend is currently bearish--especially for tech stocks. So going long is not advisable, unless you feel you can accurately time dips and rallies over daily, weekly and monthly time scales.
The most important question to be answered when acquiring (or holding) any investment is "what is the risk of loss?" If the product of multiplying the probablity of the potential gain times the magnitude of the potential gain is not at least three times as great as the product of multiplying the probability of the potential loss times the magnitude of the potential loss, then the potential gain does not justify the risk.
Also, remember to evaluate technology separately from companies, markets and businesses. There is no guarantee that any particular company (or any company whatsoever) will make a profit on any particular technology, no matter how great it is. And there is no guarantee that the stock of a profitable company will be worth more tomorrow than it was yesterday.
