MobileBurn's Michael Oryl says this phone is almost perfect - a little thing here and there, but a vast improvement over the Sony Ericsson T610.
"Only a couple of months after the release of the T610, a brilliant handset that was in my opinion fatally flawed, we have the release of its superior sibling, the Z600... For me, the importance of the Z600 is based on the fact that it is functionally almost a clone of the T610. The T610 was a great handset marred by a poor screen and even worse reception. So let's touch on those two subject first.
First up, the display. While the Z600 sports the same sized display as the T610, and one that still displays 65,000 colors, it has been significantly improved. While still not as good in bright sunlight as a true reflective display, it is much better than the T610's display. It is reasonably bright and colorful, and is appropriate for a phone of this type. Certainly we'd like to see a QVGA display like that from the Sharp GX-20 in it, but we can't have everything. I'm just happy that the display has been improved as much as it has.
The bigger improvement, I would argue, has been made to the phone's RF capabilities."
