Top laptops companies are not selling laptops to us (Pakistanis) "officially" through their website. If you read closely (especially the warranty webpages), you'll be surprise that the things mentioned on websites, for example Dell, are for United States of America. Surprised?!
Pakistan is a third world country, who only produce terrorists (beside we other products) and nobody outside care about this country. Welcome to the real cruel world.
What you see in Pakistani websites or in shops around Pakistan is that dealers/shopkeepers bought laptops in bulk from companies in USA with some specifications that they think would be more "suitable" for Pakistani market. After all they are the dealers from Pakistan, they know that our (Pakistanis) first demand is to make things as cheaper as possible. Secondly, most of us just want to showoff "that I have brand new Dell laptop" without even caring whether it has 2GB RAM or 4GB RAM because after all what we are going to do is to check email, run MSN/Yahoo/Skype, view some videos on YouTube and 2GB do all these without a fuzz. And general public is happy with it.
That being said then came a very small group of people who called themselves "gamers" who go for computers that can run games. They have to dig or customize to get laptop what they need. Then came a minor group with less population than Vatican city, who called themselves "programmers" who also makeshift with computers available in market to cater their needs.
>1) Are the laptops only available with the specs that are mentioned in the official website or can they be customized etc.? If they're available with different specs, then does it means they've been opened and not pin-packed/sealed?
Some of the websites, for example HP and many others, allow you to customize laptop (at least a little bit from default hardware) before you order it on their websites. This flexibly allow customers to get what they want. You might get different specs in same models in Pakistan, read above as I mentioned how dealers customize their orders to make it more attractive for Pakistani market. Secondly, what's "pin-packed/sealed" and "not-pin-packed"? I am happy what I get in Pakistan. I thank Allah that He still give me things to buy in this third world that first world people enjoy. It's a luxury to have same model that first world is using. 100 years back it was a dream for third world countries to even see those products in their life time that first world were using.
>2) Is Windows 7 Genuine already installed in Dell 5040 or 5050 or other Dell laptops that are coming in Pakistan?
Flip the laptop, if a key is written on the backside of laptop then get a DVD from market or download directly from Microsoft and install Windows 7 with that key (written on the backside of laptop). However, many laptops sold in Pakistani market are with "DOS". As I mentioned above, dealers/shopkeepers have to shave off as many dollars from the price tag so that Pakistani stop asking about "lower the price". Or in other words, increase their profit by installing pirated Windows 7 on a "DOS" laptop When in doubt ask the shopkeeper/website/dealer before buying that whether it has genuine Windows 7 or not.
>3) What is a better choice b/w 5040 and 5050 or suggest some other in the range from 40k to 50k ?
Research it yourself. You'll be the one who is going to use that laptop, not us. If I have to choose, I'll choose blindly with the lowest price tag. But it's my personal choice.
For how many times I have to tell everybody to research and make decision yourself. Stop relying on other people's choices. This is not 1990. You have internet, research and read on internet about each laptop's specs and reviews and make an intelligent decision based on your own findings. Would you buy Mercedes just because I said so? No, you'll buy the car that you find fit for your needs. Or maybe, majority of Pakistanis are just big babies who want others to make decisions for them. That's why this country is so f***ed up.
