I was deciding between this (Toshiba Satellite M645-S4055 LED TruBrite 14-Inch Laptop (Black)) and the ASUS 14 in bamboo (ASUS U43JC-X1 14-Inch Bamboo Laptop (10 Hours of Battery Life)) which was the same price, but the ASUS was on pre-order forever it seemed and this one was out of stock or available elsewhere for more $$. I happened to catch it back in stock one night 8/5/10. I needed to replace a 5+ yr old HP laptop and a 2 yr old HP desktop, so I wanted the power of a desktop (or near) with the portability of a laptop, and I really like the size/weight of the 14 in. This Toshiba and the ASUS were pretty even on many specs - hard drive, 1 gb graphics, RAM, keyboard style, OS, i5 processor, etc - so at the time it came down to availability and features. I say at the time because now that the ASUS is available, it also comes with a 150 GC which I can always use. That would've probably made me wait on the ASUS had that been made known when it was still on pre-order.

ASUS over Toshiba:
Longer battery life, 8 cell vs 6 cell on the Toshiba
USB 3.0 - currently don't have a use but good for the future
WiDi - I currently don't have a use for it
Bamboo finish - very nice looking, would look great just sitting on the end table!

I've used this laptop for over two months now, and it does good at what I need it for: sitting in class typing down notes, web browsing, HDMI out to my big screen tv at home watching HD videos. I also needed something that could hold its own when I finally get Starcraft 2 (yes I know it's out). A cross between portability and power, and not too far off from my HP desktop performance (Intel Core2 Quad @ 2.5 GHz; 8 GB ram; Nvidia Geforce GT 240). My graphical processing needs aren't that high, much of the software I use is from the Windows XP era, so this Toshiba's Geforce GT 330m (which performs slightly worse than the desktop Geforce GT 220, and any gamer will tell you, is *NOT* a gaming card) does its job nicely.

That said, I ran 3dMark06 on this, and got a score of around 5000 or so, can't remember exactly (~14-34 FPS at Proxycon, ~12-22 at Firefly, ~7-32 at Canyon, ~15-25 at Frost, something like that).
Final Fantasy IVX's official benchmarking program gave this a ~760 out of 8000 at 1280x720 resolution. Comparatively my PC got around ~1800 at same resolution. Those are both really poor scores, but then again I don't really have time to play much PC games these days.

Previous reviews have been comparing this laptop to the Asus' new Bamboo ASUS U43JC-X1 14-Inch Bamboo Laptop (10 Hours of Battery Life), but I'll compare to what I considered while still browsing for laptops ASUS Republic of Gamers G51JX-X3 15.6-Inch Gaming Laptop (Blue), This was 1,100 two months ago, but has dropped their price to as low as 1,000 every now and then.

Bottomline: Laptops are difficult to upgrade as technology improves and computer programs demand more RAM or graphics power, I felt the RAM upgradeable feature and the better graphics card put this Toshiba over the top. That along with the higher build quality means that this Toshiba offers good value at this price.
Best features: i5-450M processor, Nvidia 1gb GT330M, 4gb RAM (8gb expandable), Harman/Kardon Speakers, and Backlit Keyboard!

Like other reviewers I wanted a good quality, powerful, and lightweight laptop. This Toshiba M645-S4055 really had the best bang for the buck when compared to the competition.
Sure you pay a bit more for the Toshiba, but really having owned HP's in the past, I can say thatToshiba is the best PC maker, they are probably the only PC maker that can compete with Apple for build quality.

I compared this 14" to the ASUS bamboo 14" and although now Amazon gives your the $150 gift card with the ASUS, I still think this Laptop will be better in the long run. I checked out the ASUS at bestbuy to visually get a hand on the Bamboo covering, for sure its nice and I almost purchased it. But the bamboo finish felt cheaper and shows finger prints easily.

The Toshiba is better in these select but important categories:
Quality Build: The Laptop feels solid and high quality, the Fusion finish is cool and solid.
Keyboard: Backlit LED lighting (now that I have this, I can't be without it)
Graphics: Nvidia 1gb discrete and switchable graphics (GT 330M vs. 310M, the Toshiba graphics are faster).
RAM: 4gb, but most importantly expandable to 8gb (ASUS is 4gb max)
CD/DVD: The load drive is a slot not a carrier you have to pull out, this design is much better.
