Nice review, but I disagree in a few spots and have a few observations. I have had the SL55 for a week and also recently had (and still have) a 7210:
1. The reviewer had a defective unit, evidenced by the popping in the speaker. I do not have that problem. Not sure if his unit was defective in other ways.
2. RF is as good as the 7210 or perhaps only slightly worse. It is not fair to compare it to a t68i.
3. It seems like the reviewer is just too comfortable with the Nokia OS to be fair to the Siemens. I say this because I often feel that way too. But, I have used Nokias for 4 years and Siemens for only a week. The Siemens OS is fine. There are places where it is better than Nokias and places where it's worse. On balance, they're about the same. However, both the SL55 and Nokia Series 40 pale in comparison to Symbian.
4. Battery life seems to be improving over the week. Not sure why as i have not really been using the phone less. Odd. I guess I just don't understand battery technology. It now lasts a solid two days.
Overall, I am very pleased with the SL55. That's not only because of the form and style, but also because of the functionality.
