I will become a new switcher soon, from IBM ThinkPad. My interests lie on either the latest Powerbook or the 1.86GHz Duo Core MacBook Pro. Due to the limitation of the budget, I cannot go too far. The sweetest price I can get for these babes are: CAD$1624 for a refurbished 15" Powerbook G4 (1.67GHz/512MB/80GB/SuperDrive/ATI 128M VRAM) directly from Apple using a coupon I got; or, CAD$2099 for a brand new 15" MacBook Pro (1.83GHz/512MB/80GB/SuperDrive/ATI 128M VRAM) from Apple using my student's discount. Moneywise, I certainly lean towards the Powerbook since I can use the money I saved to max the RAM and I am sure it will run perfectly for me. However, I do love the option the Intel Mac offers to install Windows XP natively, and I will love to have a free iSight as I do video conferencing a lot. I just don't know if all the additional features and performance boost worth the extra CAD$500. What's more, I do have a bigger concern towards the new MacBook Pro: the NOISE issue. I read a lot of complains from HERE, and I am quite worried about it. The one thing I am not comfortable with my former ThinkPad is that the fan is always spinning at low frequency to keep the Centrino CPU at around 40 degrees, even when I was doing nothing. i.e. I am easily distracted by the noise my laptop made. This is one of the main reasons why I want to make the switch. I test drived my wife's iBook and I love it. Though it might not be as powerful as my ThinkPad, it's always quiet. The fan seldom works though the CPU temp is always above 45 degrees. The thing is, I don't mind it generate heat (I am using external keyboard/mouse), I need it to be quiet. My request to you guys is, give me some advice on which one to get, the classical Powerbook, or the shining MacBook Pro? For those of you who already got a MacBook Pro, can you justify the noise issue? Is MacBook Pro really noisier than Powerbook G4? Thank you for your attention. Your input will be highly appreciated!
