IBM all the way. Got a IBM x22 at home and at work we have a wide selection (R and T´s) of IBM laptops as we are IBM Buisness Partners.
If you cant afford a new IBM you might wanna look into buying a used one...i would personally rather get a used IBM than a new Dell.
I have a T42 at work and as much as I love that I am not willing to pay the price this cost mainly because of the brand. Used is also out of the question.
Laptops does not have any laptops that appeal to me. The T42 they have does not even have the resolution the T42 I have at work have. 1024x768 vs 1400x1050.
Sunlight readable screens, dust seals, and being as solid as they are you feel like they will last for ever.
