Not everyone's iProntos crash - mine has been absolutely rock solid for the last couple of months now. The first place to start is to ensure that you have the latest firmware installed on your iPronto - that sorted any locking up that I was experiencing.

I believe that there is still a locking up issue that Philips are still working on which (if I understand correctly) is due to a problem between the PCMCIA WiFi card and the iPronto when in sleep mode but it doesn't seem to affect all iProntos - hopefully Philips will have a fix for this soon.
