1. Preferred Brand: any brand
2. Budget: 3k - 3.5k
3. Usage: office, web browsing, gaming(most of the time tycoon games / simulator games eg: freight tycoon, euro truck simulator, etc) , 3d design and graphic design (min 8gb ram, more is encourage)
4. Preferred laptop/screen size: any but must be lightweight prefer <2kg (less than 1.8kg is good), optional to have ODD also

Not really heavy but sometimes I do the initial work for that via laptop due to the timing and mobility as I always travel.
