OK, so I went out and bought a new base model "GlassBook" as some have been calling it. It's only my second Mac, and it's my first "real" laptop (I've had other PCs, but I was much younger and generally stupid-er with them). 1) Heat: Yes, I know this has probably been discussed over and over, time and time again, but I'm still unsure of the definitive answer. I know that the older MBPs used their aluminum cases as a heat sink; is this still true with the new Unibody MBPs? Also, my temps skyrocketed to 150 degrees (F) while watching a YouTube video, and then back down to about 125 once I closed that window. Yet, my fans still stayed at the same 2000 RPMs. Is that normal? 2) How important is calibrating your battery? When I first got the MBP and charged it up, CoconutBattery reported my max charge at around 4750 mAh. Now after about 4 cycles, it's at 4064 (max) and my health is still at 100%. Is this a result of not calibrating it? Is that a must do? 3) Approximately how many cycles will I get before I start to lose health? Yes, I know that losing health isn't a bad thing and is inevitable, I'm just curious 4) I was using an Aluminum iMac prior to this MBP. In my dorm room, I'd pick up a weak WiFi connection to my school's network, but I never used that. Now with my MBP, I'd like to sit on my bed rather than be wired to my desk. I can still pick up that network and apparently connect to it, but neither FireFox nor Adium can get a connection. And when I go to disconnect, it says that I'm connected to a "device", whatever that means. Any help with that one? 5) Is there any way to reduce or eliminate the static that I get when I have external speakers hooked up through the headphone jack, but nothing playing? 6) My friend has the base model 17" Penryn MBP. Ignoring the differences in screen size and the matte vs glossy debate, which of our computers would be better for video editting, gaming, and other "intensive" tasks? 7) Apple's still busy patting itself on the back over the whole "UniBody" deal, and the press is making a big hooplah about it. Granted, it's a nice new manufacturing process and it does make for some clean looking notebooks, but what does it mean to us, the end user? Is there actually some benefit? Or is it just that we have smoother curves and less screws? Thanks for the help guys.
