FYI. There are usually discounts if you ask if you pay cash. Even from flagship stores directly from Asus I’ve gotten like 2-3k NTD off with cash.
The zenbook S 13 for me is great for travel because it’s so light and compact and the charger is also small and light. the downside is the screen size if it’s your main computer. The screen is beautiful though with the OLED model and it’s also touch screen with had some minor uses for me sometimes. I’m not big on touch screens but it does have its uses at times.
If it’s your main laptop, I would go 15in if not 14in minimum. I’m not a big fan of larger than 15in as I feel like it defeats the purpose of a laptop for most people unless they’re sometimes mobile but use it mostly like a desktop.
