Hello, I'm a proud new owner of a brand new Powerbook G4 15" combo drive. My previous computer was a 12" iBook G4 1.0 ghz. I went through a lot of decision making between the 12" and 15" powerbook. I will be a freshman in College next year, and that is the main reason for this computer. I finally decided on the powerbook from looking at it this way: When your at the store, comparing the 15" to the 12" inch, the 15" inch really seams much bigger. But I thought, once I brought it home, I won''t notice the size. I'd rather go bigger, than go small, and wish I went bigger later on. Plus, just from using the two machines in the store, I much preffered using the 15" over the 12". That's the question you have to ask. Which would you rather use? Anyways, I'm so glad I went with the 15". It's such an awesome machine all around. The display is a huge upgrade from the 12". not just size, but brightness, quality etc. I also enjoy typing on this much more with the larger palm rests. It is plenty fast for anything I'll be doing in college. I plan to add a gig stick of ram when I get more $$. I had to use my 12" iBook to configure it for the new owner, and I just can't believe how I ever got by on it! lol. I'm spoiled. Bluetooth is cool, I'm able to connect to the internet through my bluetooth cell phone anywhere! (Verizon). I've already started venturing into doing things I never did with my iBook, such as making an iMovie. And the automatic screen dimming and keyboard lights is... Much much cooler than I originally thought. Battery life is great. Plenty of time for those times when I'll be working off the battery. One other thing I noticed, is I'm getting much better airport reception than my iBook did, either that or that's just the difference between Tiger and Panther, which other users have noticed. Heat: It's not as bad as everyone makes it out to be. On average, under heavy load it runs 10-15 degrees F cooler than my old iBook. The fan is also quieter. Guys, if you are having a hard time deciding, spend the extra $300. You'll be glad you did. Unless you need ultra ultra portable, 15" is where it's at. The 15" is actually useable, you don't need to plug into an external display in order to be productive. However, it is still a lot of money for a computer. Be sure it's what you want and something you need/will use beforehand. I use my computer everyday for hours at a time. Use my own computer at work, and soon will be using it for school. I need a good computer for school. That's my justification Thanks for letting me share my thoughts. I may post pictures if I get a chance (even though everyones seen a 15" PB). Have Fun!
