A good point!
After living with my old Acer laptop for the last 4 years (15.4", centrino 1.6, 512 ram, 80gb HDD, X700) I've been much in need of an update - until recently it just hasn't been feasible.
I think having this laptop tought me a number of things though, that helped me to decide what my next laptop would be:
PortabilityBeing a 15.4", my current Acer isn't particularly lightweight, and having it in a heavy leather bag doesn't help. It only takes about 5 - 10 mins of walking with the laptop before it starts to become [i]very/i] uncomfortable (to the point where I start to get red marks on my shoulder from the strap digging in). The first thing this told me is that my next laptop must be somewhat lightweight. Being a uni student I need something I can carry around frequently with comfort. Also, since IT is mostly likely going to be my future occupation, I'm likely going to need something I can carry from place to place.
StorageConsidering I do a bit of IT based work (and plan to do more in the future) I found the storage of my current laptop parrticularly limiting. After trying to run a dual boot (XP/Linux) system on an 80GB hard disk, I can confirm that it doesn't work too well. It allows you to install all the necessary software, and that's about it. Next thing I confirmed is that I wanted something with at least 200GB of hard disk space. This would allow me to (if necessary) run a dual boot system with 100GB dedicated to each O/S.
PerformanceI use my laptop for a few different things over time. Image editing, some web designing, multimedia, web surfing, etc. On a 1.6 centrino with 512 ram everything runs barely sufficiently. All it takes is an attempt to edit a 25mb bitmap image to teach me that my next laptop has gotta have some balls.
GamingWhatever I buy, it is most likely that 90% of the time it will be used for uni / business use. This means that gaming is nowehere near a prority, as I have a ballsy desktop I specifically built for gaming and multimedia. However, on the odd occasion my mate will call us up to have a LAN night at his place for a little battlefield, medal of honour, Raven Shield, or whatever else is the flavour of the day. Tagging along my 20kg twin-PSU behemoth, 24" LCD and keyboard/mouse is hardly convienient, so I need something that has some gaming capabilities. Becuase of the limitations of my other mates' laptops, we never play anything too stressful - but at the least I need something with a bearable dedicated graphics chip.
ConnectivityConsidering I plan to keep the laptop for several years, it's important to consider potential future connectivity requirements. USB is nice, but for something that I'll likely use in the IT industry it's important to have as much available connectivity as possible - firewire (being a common interface) and eSATA (being a potential future interface) are not necessary, but would be good to have. If eSATA really takes off, we could see the drop of USB hard disks in the next couple of years so I'd like to have the future covered for.
Multimedia If I want to watch DVD's, I'll do it on my home computer. If I want to listen to music, I have my newly aquired reference headphones and a MP3 player in my phone. That means multimedia is not a priority. I don't care how loud the speakers go, and don't have how big my DVD's look.
InternetMobile internet would be nice, but I've done without it up until now because I just cant be bothered carrying around an external USB model everywhere I go - if I'm somewhere like in a car, on a bus, walking around uni or whatever it's not not feasible. That said, having to rely on the presence of local internet access is unfeasible.
So in the end, I had Identified my requirements. I essentially needed a compact laptop with high performance, a big hard disk, dedicated graphics, decent connectivity and mobile internet (if possible) for roughly $2,000. Once I identified these requirements, all I had to do is research.
I crossed out HP from the get go because their lack of service and reliability irritates me so much I've grown a personal grudge against anything with their name on it.
I crossed of Sony, because their compact laptops in my price range didn't have specs even close to what I needed.
I crossed off Lenovo and Toshiba because even though they had some nice compact laptops somewhere around my price range, all of them sacrificed hard disk space for portability (having 160GB hard disks at the most).
I crossed off Apple because getting a Macbook Pro with even HALF the spec of what I was looking for would cost me $2,500+
That left ASUS as the only brand - and with them I found three options.

Was a majorly tough decision but in the end, I really wanted the connectivity (12" had 3x USB only), Vista Business (for back up feature) and 3GB ram (to account for turbocache use) so I sadly scratched the F9 off the list.
I also really wanted the wireless internet capabilities, so the that scratched the F6 off the list - which narrowed it down tot he V2S. It's a little heavier and larger then the other two models, but at 2.3kg it's hardly a brick - and the extra display size wouldn't hurt come coding/gaming/image editing time. Being a business model, it also has a non-reflective screen which doesn't hurt use in high light areas. So even though it was a bit more then I wanted to spend, I placed my order for the V2S on Sunday.
I guess what I'm trying to show here, is that when deciding on a laptop, you reall need to have a good think about what you are using it for, what you need and want, and what you dont need and dont want. You can't always get all of the things you want, so sometimes you have to consider which compromises you can live with the most. If you look at some of the above criteria that I looked at myself and have a good think about each one, it may help you identify what you need in a laptop - and this will help you narrow down your choices.
Once you've narrowed down to a handful of models, then you can try to find some shops that have them and see which one feels the best for you, or which one can be aquired at the most suitable price.
Just make sure you try to consider everything possible, becuase the last thin you want is to spend $2,500 on a laptop, only to look back and regret it in a year because it can't do what you need!!
Hope that helps
