My craptacular Compaq Persario has lasted through more airline miles than I could imagine. It also works well in the frozen tundra of Alaska and the desert heat of Southwest Asia. It has been dropped, kicked, stepped on and keeps on humming. It has an AMD K6-2 550 in it.
With the new HP/Compaq merger I hope the HP laptops take back burner to the Compaqs. We just bought 3 new HPs at work and they sucked out of the box. The Dells we have still work but all have different problems. They are beat to H3ll though, so no complaints here.
It sucks taking 2 laptops out in the field because one has network access and the other has a working COM port.
