Business laptop because consumer laptops are unreliable and junk!

Looking for a BUSINESS laptop for the following reasons: (1) Supposedly more durable and reliable the internet world tells me; (2) Allows the user to upgrade RAM, battery, HD, etc; and (3) Has a standard three year warranty.

I will NEVER buy another consumer level laptop again or a laptop that has soldered on RAM, HD, or battery.

1) What is your budget?
$750-$1500.

2) What size notebook would you prefer?

Anything under 17".

4) Are there any brands that you prefer or any...
