Okay, I got around $1,800 for the 6000, but you're going to use a coupon, right? That would knock it down to around $1,200 or so.
I really recommend the Dell Inspiron 6000. The Toshiba seems to be like the 600m in the way of outdated technology. I'm not sure if it is, but I can find out later.
First of all, the processor on the 6000 is slightly faster.
Second, the maximum memory for the 6000 is more. The Toshiba is only upgradable to 1.5GB, while the 6000 can handle up to 2GB. This is one reason I believe the Toshiba is made of outdated technology.
Third, the memory for the 6000 is faster than for the Toshiba. The Toshiba memory runs at 333MHz, while the 6000 runs at a minimum of 400MHz, but can run at 533MHz.
Fourth, the graphics card on the 6000 is much better than the card in the Toshiba. Granted, the x300 is not a gaming card, but it is much better than integrated graphics.
Fifth, the Toshiba will use 128MB of memory for graphics. The 6000 has a dedicated graphics card, so all of your RAM will be used for its intended purpose, and not video.
Sixth, the wireless card in the 6000 is better. While the a format might be outdated, it might still be used, which means the 6000 will be more compatible. It's a good feature to have, just in case.
Seventh, the battery life is better for the 6000. You can about 3-4 hours on the 6000 with the standard battery. With the extended battery that you are planning to get, you could get more than 5 hours. The Toshiba's average is about 3.5 hours.
Now, last, but definately, definately, not least, the warranty. You would get a 1 year warranty on the Toshiba, and I really doubt that's anything like complete care. With the 6000, you would get 4 years of warranty plus Complete Care coverage for that 4 years. Now, it's true that you can buy an additional warranty from CompUSA, but the price is ridiculous. The warranty would be a 2 year warranty, or a 2 year warranty plus screen protection. That would make me assume that if your screen broke and you didn't get the screen protection crap, you would be screwed. With Dell, that's not a problem. In fact, I can't even tell what the Toshiba warranty covers. At least with Dell, you know what you are getting before you even buy the system.
My personal opinion is that Toshiba sucks. I know people that say otherwise, but a lot of people say that the Satellite series sucks. They say the Terca series is good, but a lot of people agree about the Satellite series being crap. If I were you, I would not even consider Toshiba. If you want to consider some other quality systems, I recommend IBM or Sony. Both of these can be overpriced, however. I don't have much experience with anything else, but I've heard that Sager and Asus are good, too.
