We have a macbook pro and I still call it a laptop. Same as my ipod is my MP3 player. I don't really buy into the culture.
OT: Don't get a mac unless you like dealing with boot partitions and constant short fallings. Having fucked around with bootcamp for a while now, it's really not worth screwing around with. FFXI sometimes hangs on the laptop, it's just extra hassle setting it up and configuring everything, and their hardware isn't the same bang for bucks you're going to get if you buy a custom PC from a manufacturer such as alienware or if you make one yourself.
Plus, upgrading is pretty much out of the question unless you like seriously voiding your warranty and removing 3 kilo heatsinks with lots of small parts around to get knocked off.
Building your own computer isn't as hard as your friends and relatives might think. Imagine legos with more expensive parts and potentially deadly currents (I'm just joking about that... You really do deserve to die if you attempt to fit your CPU while you have the power supply plugged in.) Most instruction manuals for major motherboard manufacturers have instructions on how to correctly install and configure everything, and most other things are simple enough (screwing components in, plugging the right connectors into the right devices)
