In the end I come away with no major complaints about the N90Sv. The notebook has decent performance, but doesn't break any performance records. The integrated Blu-ray player is nice, especially when coupled with the great 18-inch screen. The real issue with the N90Sv for me isn't the machines performance as much as it is the price for performance. Much of the cost of the machine is tied up in the Blu-ray drive and the fantastic screen.
If gaming is your bag, the Gateway P-7808u FX is nearly identically priced but offers much higher performance than the N90Sv, but it lacks the Blu-ray option. The N90Sv is a very capable multimedia notebook and I wouldn't hesitate to recommend the machine. Just be sure that you plan to use the Blu-ray drive heavily to justify the cost of the machine. If you won't really use the Blu-ray, you can get significantly more performance elsewhere for the same money.
