Satoshi's Wireless Weblog: User Interface is an Art: Java benchmark. Hattip to Satoshi for finding a benchmark site. Amazing to see how different performant is at "Jbenchmark":http://jbenchmark.com. There is a 10x difference in performance. For instance the Motorola 720i is at 500 utils while the Sharp sh53 is at 1500 and the Nokia 7650 is at 2524.
