Dear forumers, I would like to ask for your advice regarding laptop choices, as I've never ever owned a laptop before in my life, but due to recent circumstances, I'm forced to purchase 1.

Here are my questions :

1) Which laptop brand is more reliable, as in doesn't breakdown often or overheat or spoils easily due to handling problems? Dell, HP, Toshiba, Asus, Sony, Apple.....

2) What laptop specs or model is more suitable for Autocad and Autocad Revit usage? I presume it requires more emphasize on the graphics and the ram.

3) As it is used primarily for autocad draughting, what monitor size is more suitable? I personally liked it to be the bigger the merrier, but mobility is also an issue, or else, don't even bother considering a laptop, rite?

4) Budget around RM 3-4k, as I don't expect it to be the best there is in the market, just average with more emphasize to draughting works will do.

5) Is it cheaper to buy laptops in Malaysia or Singapore, excluding the transportation expenses factor?

Thanks in advance for the productive information.
