IMHO, go for something that has a
proper warranty, and a
big screen
You don't want to be spending R25k on something with a one year, take-in warranty.
I have a Fujitsu
LifeBook N532 (i7, 16GB RAM, SSD + HDD, 17.3" screen @ 1920x1080), with a
port replicator
With a clean install it booted in about 8 seconds to windows.
We also have 3 year, on site warranty, and only in exceptional circumstances will the laptop be send in.
In my experience IDE panels take up a lot of space (visual studio, eclipse etc) and then 1366 x 768 is a no no.
