I was a mac evangilist in the mid 80's but once I joined the corporate world I gave it up since Windows PC was the norm,,... I'm now a small business owner in search of a new laptop and just about convinced myself to buy an IBM ThinkPad T40p with WinXP when a friend of mine influenced me to visit an Apple retail outlet.
Well after a session with an Apple representative, Apple still has a way to excite me about a computer. I was particularly interested in the PowerBook G4 15" with Panther OS. As a result, I've been getting educated on some of the Discussion Forums. So, I'm ready to make a purchase and I'm favoring the PB G4 15" over the IBM ThinkPad T40p but there are some fundamental shortfalls with the PB that I'm hoping some of you can address,,...
1- Although Apple promotes the battery life at 4hrs, we should probably expect no more than 2hrs with DVD or intensive processing applications. This is a bummer since a centrino-based pc, such as the IBM ThinkPad, can support as much as 5hrs with intensive processing applications (i.e. conservative estimate). Some of the threads on MacWorld and the Apple website confirm this PB shortcoming.
Q1: Is there a possibility that within the next year, Apple can provide a single battery that would improve the battery life?
2- The now infamous "white spot" screen problem experienced with PB G4 15". It seems from the threads that it is resolved,,...
Q2: Any further thoughts?
3- I've read on some of the Apple website Discussion Forums that this PB can run as HOT as 125F or more,,... that is damn HOT!
Q3: Will this issue be improved with new PB batches? If so, is there a serial number track that I should be aware of?
4- Compatibility between a Win PC and a Mac has gotten better with Panther but I still have some reservations,,...
Q4: Will I be able to transfer WinPC files with extensions such as .pst, .exe? For example, does entourage support .pst files from outlook? Also, I've been reassured by the Apple representative that file extensions with the M/S office suite are fully compatible between WinPC and Mac,,... any further thoughts?
5- I've heard rumblings about a new mac OS update in 2004,,...
Q5: Is such an update driven by cosmetics, useability and/or WinPC compatibility challenges? If so, what key features are expected with this new mac os?
In short, my heart is with Apple PB, but I still like the battery life and lack of HEAT with the centrino-based PC's,,... yes, the s/w on pc's is no match for mac's but I'm on the road quite a bit using the laptop on my lap,,...
Thanks in advance for the advice,,... cheers!

PS. Looking for a reason to become a mac evangilist again. Great forum!
