When the next upgrade of the Powerbook
I hear around the apple will wait much more than a year before producing the intel powerbook (they will give a try at first with the ibook).... so when and what will be the next generation of powerbook before the switch??
Still any possibility for a G5 or some thing similar that would give a real boost to the performance of those splendid creature??
Thanks to all

Says who?

There is a slight possibility that the Powerbook will take the MPC7448, but I personally doubt it. It all depends on internal Apple schedules and contractual obligations.

Just don't bet your house on it
If they are going to wait for Merom, than Powerbooks with 7448 G4 in March, unless Intel is willing to give them pilot production Merom chips, which means May or June (but this seems unlikely).

bzzzzzzzzzzt wrong. Merom is a further improvement of the core which is supposed to be up to %30 faster per clock. The 64-bit support has to be there for the basis of Conroe and Woodcrest.
Endian.net on Merom
Mobile processor succeeding Prescott-M and Yonah built on a 65 nm process. Accompanied by the Crestine chipset. Recent rumours claim that Merom is a major new core design with multiple cores and, depending on version, 2-4 MB of cache, which will also form the base for the next desktop chip, Conroe. Said to consume about 45W.
Earlier said to launch in 05-H2 or 2007.
Merom is part of the Santa Rosa Centrino platform, succeeding Napa. Said to be used in future Macs.
Mike's Hardware on Merom
Intel Merom Mobile processor, the successor to Jonah and part of the Santa Rosa platform, is expected to be released in H2 on a 65nm process. Merom is a Dual Core CPU combining the architecture of NetBurst and the Pentium-M to achieve both high performance and lower power consumption. Merom utilises the FSB and EM64T of NetBurst, but is largely based around the Pentium M architecture. The CPU is a 4-issue design (compared to the 3 issue cores of the Athlon 64 and Pentium 4 architectures) with a 14 stage pipeline - significantly shorter than that of NetBurst CPUs (from 20 in Willamette to 31 stages in Prescott). The shorter pipeline will ensure that Merom and it's derivatives will not clock as high as Precott, but it will likely clock as fast or faster than the Athlon 64 - i.e. around 3Ghz. However, the IPC of Merom is likely to be better than the Athlon 64 due to it's 4 issue superscalar design and vastly better than the P4.
Merom will feature 4MB of L2 cache shared between the two cores and will feature a direct L1 to L1 cache transfer system between the L1 caches of each of the cores to improve performance. Merom will also feature a number of enhances prefectching schemes to enhance the use of the caches.
Merom ...sounds like it's worth waiting for and any fool that buys a Intel iBook for speed deserves what they get.
