If I were to get a new laptop, I would get a windows maching. But, you need to determine what suits you.
In your search for the right machine I think there are four things you should consider:
- Price
- Build quality
- Warranty
- Style
Viruses are not included because, lets face it, not many people get viruses anymore. I have not gotten a virus in the past 6 years, and I only know of one person who got a virus in the past 2 years. I dont think it will be too wise to decide your laptop based on susceptability to viruses
Macbooks, tend to have OK build quality, good warranty, and good style (if thats what you like). But in terms of price they are greatly overpriced, and the build quality is OK (better for macbook pros)
In comparison, Asus laptops have good prices, good build quailties, good warranty, and the style OK (depending on your tastes)
Hope this helps
