Hey guys, i need recommendations for a laptop.

1. Preferred Brand : Lenovo, but will accept other brands. Preferably not Dell...
2. Budget: 3.5k +-
3. Usage: General usage. Not much gaming.
4. Preferred laptop/screen size : 15"+

Specific requests: Thin, Lightweight, hopefully ultra-book tier, with long lasting battery. Touchscreen not needed, but not necessarily avoided (i'll just not use it).

Thanks in Advance!
