Looking for quality laptop

Hello,

my over 5 years old HP laptop just died and now I'm looking for a new one. I use my laptop as a desktop (with monitor, keyboard and mouse plugged in). I prefer it because it's silent and doesn't draw much power compared to a normal desktop. I run it 24/7. I use it mostly for surfing, watching movies, developing software and occasionally playing games. The new laptop should run stable and last as long as possible. I plan to have it for at least the next 5 years. For the heavy lifting I have access to the high end desktop of my wife.  


Here I filled out the FAQ:

1. What is your budget?
I want to spend as little as possible while still meeting my expectations but let's say the upper limit is 800€ (1100$ / 700£).

2. What is the size of the notebook that you are considering?
It will always sit on my desk so I don't care.

3. What screen resolution do you want?
Since I use an external monitor it doesn't matter.

4. Do you need a portable or desktop replacement laptop?
Desktop replacement.

5. How much battery life do you need?
It will always be plugged in, so I don't need any.

6. Do you want to play games with your laptop? If so then please list the games that you want to with the settings that you want for these games. (Low,Medium or High)?
The heaviest I plan to play is Counter Strike: Source on medium (or even low) settings at at least 30 FPS.

7. What other tasks do you want to do with your laptop? (Photo/Video editing, Etc.)
Some heavy surfing, developing software.

8. How much storage (Hard Drive capacity) do you need?
Everything above 100 GB is okay.

9. If you are considering specific sites to buy from, please post their links.
I have no preferences.

10. How long do you want to keep your laptop?
As long as possible.

11. What kind of Optical drive do you need? DVD ROM/Writer,Bluray ROM/Writer,Etc ?
I would even be okay with none at all.

12. Please tell us about the brands that you prefer to buy from them and the brands that you don't like and explain the reasons.
From what I've read I would prefer Asus and Toshiba. I've read that they build the longest lasting laptops.

13. What country do you live in?
Germany.

14. Please tell us any additional information if needed.
It would be nice to have at least 4 USB ports, I always missed a 4th one with my last laptop. But it's not a must.


Thanks for any suggestions!
