I have never owned a laptop, thank goodness. Seems like the silliest thing to lug all of that weight around, when you travel. Everything I need I can do at a desktop. I am not in a business where I work on the road or in the field living out of hotel rooms and meeting clients face to face everyday.
I hear people talk all of the time about how you can be more efficient and productive with a laptop when traveling and such. The most productivity I see businessmen with laptops do is check e-mails, surf the web, play games and watch DVD's. Does not seem efficient or productive to lug around 10lbs worth of equipment for those uses.
I have a PDA, mobile phone and a USB flash drive. I read books on planes not watch movies.
I can see having a laptop for home use because of space constraints but to lug one around for minimal business use or entertainment does not nake sense to me.
