Mid-range Laptop Help Required

I’m in need of a mid-range laptop that has proven its reliability over time.

The main things it will be used for is:
- Emailing, web surfing
- Skyping
- Watching movies, maybe blue ray
- Photo storage
- Biggest software I’d run would be @Risk and Autocad (rarely)

Please let me know your thoughts on which brands might be best etc. I'm looking at a budget of around $1500
