Yes, if the output voltage and ampage are the same, at the same time, the dc connector is the same. Otherwise don't use a toshiba laptop charger to plug in a lenovo laptop charger.
no, altough lenovo features dd3 ram and high speed processor but it can't compare to toshiba.
I Would Think Lenovo,Apple or Toshiba Are Good
Lenovo isn't a good laptop maker. It really depends on what you're willing to spend.
Mac
I would say Toshiba
toshiba is better in my opinion but it depend what windows you are getting
I would say Toshiba over gateway.
Apple Mackbook Pro Sony Vaio Dell Hp/Compaq Acer Toshiba lenovo
Depends what you want it for. If you want a laptop for gaming then go with the Toshiba. If you want a laptop fir everyday use like the Internet, go for the Mac.
Toshiba Laptops are one of the better ones out there as far as I'm concerned... Better than Dell & HP
