I have only had my E61 a few weeks now and so far it has been perfect (once I discovered Web problems with TMO Hotspots and used Opera instead) - no random resets, great reception,etc. With all my previous WM5 devices I have noticed a gradual degradation in performance, an increase in random resets and just a general overall decrease in my satisfaction with the device over time. WM5 appears to "age" over time and in the end usually requires a hard reset to restore to the original performance.
For you longer term E61 owners: Do you have the same experiences with E61s or has it continued to be stable over a long period of time? Hate to get too excited and recommend this device to friends if trouble awaits me downstream.
Thanks for any info on your experiences,
Frank
