HP NC6000.
There are 3 laptops I'm very familiar with. 1) Dell 600m (i have this), 2) IBM T41 (my uncle's laptop), and 3) HP NC6000 (my mom's).
They are all 14.1" screens with Dothan/Banias. IMO, the 600m is a really cheap build. While Dell support is fast, I don't like how my HD and mobo failed. Furthermore, I hate the cheap plasticky hollow feel of my laptop.
IBMs are good quality, but my uncle has had it fail before completely and had to send it back. I don't like how they're not really aesthetically appealing, and have old skool keyboards/design. Otherwise, its all good.
Dell uses cheap DDR266 while IBM uses 333/400 modules. Both comps have Radeon 9000s. I believe you can get a 9600 with a T42 nowadays.
My mom's NC6000 is just sexy. I love the build. It's solid, and has no cheap feel to it. I like the design and it's high quality. It has integrated Bluetooth (something I could use with my Motorola V600) and a Radeon 9600 (which I could use as well for gaming). It's slightly heavier than my Dell because of the build I guess. The plastic is thicker so you can't feel its hollowness, and the whole cover is just more solid. My cover is all scratched up, but my mom's laptop is just nice.
I wish I could trade, although I like my SXGA screen and my faster Dothan.
My opinion is that 15" screens are huge. 14.1 is as small as I would go. Any smaller, the keyboards get ghetto and the screen is too small for my eyes. I like SXGA, so 14.1 works. Furthermore, these are all 5 - 6 lb laptops. Thin and light. Not ultra thin, but portable. My laptop weighs in around 5.3 lbs and the T41 is like 5.5? The NC6000 is closer to 6 lbs. You can tell which has the better build just based on these specs. At roughtly 1.3 - 1.35" thick, these laptops are easily carried around. Forget your 15.4" widescreens. My friend's Dell 8600 is like 7 lbs w/o DVD drive and battery? Throw that in and you're close to 7.5. Lame.
The only downside of the IBM and HP are that they are a bit expensive. If you can find employee discounts, that would be awesome. This HP laptop is no cheap crap. It's not the nubby ZE or ZV lines. NC lines are business/office lines (like the Dell Latitudes), and are high quality. Inspirons are nubby. Yes and I say that to my 600m.
