The BBC reported a global survey on what people want from their cellphones - the main feature was battery life! Personal portable devices need to have a rock solid OS (not WM5!), instant on and a good battery life.

Totally! That's so true ... many ultra light notebooks today already deliver on 6.5hrs or more ... but they only give 2.5hr ... and have the cheek to say that its not really a big deal because power outlets are everywhere. *duh*
Point to note however is that HPC (the original HandheldPC devices dating from 1997~2001) used wince1.0~4.1 and they had 8+hrs batt life, so I doubt PPCs have poor batt life because of the OS. A PPC running PPC2002 uses WinCE3.0 as its core and has paltry batt life while a HP Jornada 720 HPC running HPC2000 uses the WinCE3.0 core as well but has 8+hr batt life. The distinctly I believe goes into the hardware and also the use of TFT (PPC) vs DSTN (HPC) screen.
However the later HPCs such as Sigmarion III, Intermec 6651, NEC MobilePro 900 series all uses TFT LCDs but still have 6~8hrs batt life, so I believe its the hardware design itself and not the OS.
Either way, I agree with jah that MS and its OEM partners are really messed up with hw design and batt life. *BUM*
