N, to date Revenue has been good, but the price of a stock is more dependant on it's earnings than revenue. 
As the saying goes anyone can have great revenues selling new Ferraris for $100k, but your earnings will be negative.
So far, as a rule, revenue great, earnings mediocre, to say the least. They need to turn earnings around. Economy of scale may help, but for me, as I said before, it's the services section that is starting to grow that got me interested. Together, of course, with some bigger contracts.
Time will tell.
