I'd recommend that, whatever you purchase, make sure to get all of the same laptop make/model. One client I have insists on buying used, cheap laptops from the local discount computer store, and bless her heart, first she doesn't bother to consult with the computer expert she pays to maintain these dinosaurs, so we have a lot of single-core processors running WinXP Home in a professional, networked environment, but worse, each of the laptops is completely different from any of the others, so each computer has it's own unique way of "how things are supposed to be done", most particularly (my most strident bitch and complaint) is that worthless piece of shit the "Intel Proset Wireless Manager" and the dumb-ass Dell wireless device driver that disappears when you uninstall "Proset".
Meaning, they've slaved the driver to the wireless manager software. You can't have one without the other. The wireless won't work without the shitty software. So you have to have it installed and running, and then figure out how to have Windows manage the wireless, because if you don't, then you have to teach multiple employees how to fuck around with the piece of shit Proset.
Ugh. I've forgotten how much this pisses me off, until just now. Somewhere. Somewhere, in my mind's eye, there is an engineer. A software engineer, and he works for Dell. He's asian, in my mind, maybe japanese, and he lives and works in Austin, Texas (just up the freeway). And, in my deepest, darkest and most satisfying fantasies, I have him hog-tied and suspended by his feet in the basement of an abandoned parking garage, and he is begging for his life. This is the guy that decided it would be a good idea to force-feed that shitty Intel Proset Wireless Manager to unsuspecting, paying customers, and as much as I would like to share exactly how I torture this person WELL BEYOND death, I cannot as it is simply too wonderful to share.
I must keep this joy all to myself, and pray to the good lord above that someday he may see fit to make this fantasy come true. But don't worry, I WILL videotape it, and upload it to YouTube so that all the other computer techs that have had this nightmare will be able to fap for the rest of their lives. Monetize THAT you blackhat marketers!
Whew! Time for a cigarette. Damn. I quit. Anyways, OP that's my contribution. Buy all the same make/model computer, and if you ever find out the name, address and phone number of that software engineer, you can repay me by sending to me via PM.
