Hi guys, can you all recommend me on a laptop?

1. Preferred Brand:
None. I do like the design of Lenovo's new laptops but no particular preference.

2. Budget
2.5k, but willing to go up to 3k it's worth it.

3. Usage
Web browsing, music making (using software like Ableton Live, Guitar Rig, etc), video editing (Sony Vegas), movies, light gaming (maybe just stuff like Dota2?), video calls (so preferably has good cam and mic).

I hope to get one with at least 3 usb ports, with at least 1 still using usb2.0 (because 1 of my hardware, audio interface Line 6 apparently can't work with usb3.0)

4. Preferred laptop/screen size
14-15 inches.

Thank you for any help sifus!
