i have a Dell for personal use and a HP for work, tbh i barely use them at all.
both are mid spec so not really powerful enough to do demanding stuff and screen res does not go large enough forr my taste.
i just dont want to use them, at work it's too much hassle to carry around and keep powering on and off for the short time i might need it.
on the note of carrying them around, the above are not really spectacularly big but i'd really love a black macbook

small, powerful, looks good, can cope with any app u want to throw at it, apart from gaming which i could never do on a laptop anyway.
