I don't have a problem with it being heavy, it's just more convienent. Plus it's a portable gaming rig, which makes taking it around easy, and it just all around kicks ass at everything I use it for.
Plus heavy laptops have those nasty desktop processors which tend to heat up so bad that it completely bogs down the performance, and eventually fries the motherboard. The pentium M uses less voltage, thus creates significantly less heat, which runs the processor at max performance at all times. But for saftey reasons, I won't overclock the processor.
I'm staying at a hotel in Columbus Ohio right now with my friend working on a house project out there, and I am running on Wi-Fi- playing on my friends WoW account, and I love it.
