We've already had a taste of Eclair, so the first generation Android UI should be no revelation. But for the review to be complete, we'll go through it once again.
The Donut in the Acer Liquid is a mature implementation that has been optimized and free of bugs. It feels extremely zippy and to be honest it should. There's a Snapdragon inside (downclocked from 1GHz to 728MHz), and the OS seems to take full advantage of it.
Since the Acer Liquid is the first Android-based smartphone powered by the Snapdragon CPU, we decided to do a benchmark and see how it will stack up next to the upcoming phones running the Android OS.
We used 4 different applications which we found in the Android Market - Benchmark, BenchmarkPi, Neocore, and MemBench. All of them can be downloaded for free.
