I have one, I do all my work on it and because I am in college I don't have a desktop - so this is my baby. If you are looking for good laptops I would look into Lenovo (they gook over IBM laptops). Though, their name might not be as great as "Dell" or "Mac" they offer great hardware for an unbeatable price.
But don't have good battery life/internal time clocks. My Toshiba Satalite, lasted only 4 years. It was big, clunky, and had HORRIBLE battery life (3 1/2 hours on low) I say you should get an ASUS laptop. You can get a good one for about $600. It has about 10 hours on full batteries, built in wifi, built in SD card slots, disc drive, and webcam/mic.
I've been running Toshiba since 2005 and I've had pretty good luck with them. (I've had a Satellite M40, a Satellite A100 and I currently have a Satellite M300.) Battery life has been pretty good on the other laptops (between 3-4 hours on the M40 and over 4 to almost 5 on the A100), but on the M300 it's at about 2 hours when set to long life. (This doesn't seem to change whether I have my wireless on or off either. ) But hardware wise it's decently powerful. Enough for me to run quite a few games even by today's standards. (Though they might not be as good looking as if I had an Intel i7 with 16GB of DDR3 and a Nvidia 8800GT or so graphics card.) But it gets the job done.
If I was looking at getting a new laptop, I'd get another Toshiba. The Satellite A500 looks to be pretty good to me. Though it depends on what you're going to be using it for... If you want it for gaming then be sure it has the dedicated vram. For anything else, it probably doesn't really make that big of a difference if it has the shared vram.
I have a Toshiba Satellite notebook, and I'm very satisfied with it thus far (even though I'm stupid and spilled on it twice within a week of getting it). It's lasted over a year, and that's good for me.
I have a Macbook Pro - it's really a great computer! I recommend you go to one of their stores and demo some of their computers. It's really fast, and stores lots of spacex
Gotta agree 100% with the overpriced issue. I personally haven't seen too many mac laptops that are less than 1200$ whereas I've seen tons of regular Windows laptop that range from 600-1200$ And the hardware on the Windows machines is usually better. So pay less for more powerful hardware? Yeah, I'd much rather that than having a mac.
My laptop is soon to be on its way out, I shall be getting a Dell next I think. I have always viewed Dell laptops to be very good build quality and the components to have a good lifespan. they work well with Linux too and are customizable on the website.
