We have in our company several brands, HP, Acer, Asus, MSI, Lenovo. All i can say is that MSi is reliable because there were no issues encountered.
2 of our Asuses burned its batteries, 1 Lenovo had it LCD blacked-out same with the Acer. HP so far no problems but I maintain two in my family and issues sofar is the thermal shutdown.. After cleaning the heatsinks and re-seating with silicon grease, its stable again.

For Netbooks:
I've owned 2 MSI Wind U100(with BT) both sold after months use, and now using Wind U123H (the one with N280 and 3.75G adapter). All i can say for those models they are superb, stable, no heating issues. 9cell bat last from 9pm to 10am but i replaced it with 3-cell for more portability.

To note, i just checked/ tried to repair my friends 6months old AAOne with annoying LCD lines and opening it was really pain in the ar$e. Don't know with Asuses if the iron-like heat produced at the bottom was already resolved..

Pics of internals, look at how Acer LCD ribbon cable was arranged, and SMD's arranged as compared to MSI.
