hi, need recommendation;

1. Preferred brand : any
2. Budget : below 2k
3. Usage : business use only, mainly words/excel(the simple stuff), but able to take heavy loads on multi-tasking(such as opening alot of browser tabs, i don't know if this is a thing to consider regarding performance but correct me if im wrong)
4. Screen Size : 15 inch

- if possible an ultrabook for that price range?
