What laptop should I NOT buy?

I honestly suck at technology so I need a simple and an excellent performing one.
What laptops do you guys have? Tell me what you don't like about it.

I'm looking for a laptop that is:
- 11inch
- Weights less than 1.5kg
- Long battery life
- Has >2 USB slots
- SD card reader

I've also noticed that a lot of the recent laptops don't have CD drives in them, do you think its necessary to have one?
You may have seen me ask this question before. I've asked this question so many times but I never get constructive feedback!

I was thinking macbook air 11 but like i said, i suck at technology so I have a feeling it's going to take me forever to adjust to whatever software it has (not windows) because I work on a windows right now.

You might want to try Lenovo laptops as they are lightweight and has a long battery life indeed.

Just what ever you do DON't buy apple computers. For what you are paying for they are huge rip offs, Also I have not used a CD drive in months if not years
