It still miss a mobile version of my Google calender. Hopefully that's coming this year. Google, please ?
If mobile operators would charge resonable rates for the datatraffic then I think 2007 will become the year that we all starting to read mail on a phone now and then. Because the above three apps almost transform every phone with a colour screen that can execute Java Midlets (an that are a lot of phones) almost into a Blackberry. And let's face it, don't we all want one like our CEO just like we wanted a GSM back in '98 because all important people already had one ?
