What I found good about this device was that it was simple to use as one has a stylus, touch key to flick through the menu's and a scroll button. It is also compact and lightweight unlike similar devices from iMate or Palm.
A top of the range 3G touch screen phone the device was not without its problems but these were easily overcome. When travelling, I always set my portable device on the local time for the region I am in with my home time set as the second time. The only problem with this device was that it kept resetting itself to my home time not the region I was in time. This in turn stuffed up my diary.
The phone also locked up every so often and the only way to fix this was to take out the battery and reset which can be slow as one of the setbacks with this phone is that it takes several minutes to boot up from scratch and entwer a Sim code.
In addition I travelled with a notebook running Vista and despite the enterprise version of this software being released in November 06 Sony Ericsson had failed to post a driver that allows this device to connect to the new Windows operating system.
But despite this I would highly recommend this phone as an all round good organiser. The phone comes in a choice of two very colours which are granite black & crystal white coloured casing. The casing is extremely thin considering all the features that are in this phone. During my trip was able to compare the M600i and the new iPhone from Apple and what is crystal clear is that we are moving into an era when high quality touch screens in phones will become the norm for many power users. Ironically I felt that the M600i was of a higher quality than the Apple offering however these are early days and what was shown at Macworld were prototypes.
