iPad 1 3G	3.3	34	16
iPad 1 Wi-Fi (iOS 4.2.1)	8.1	25	14

Best results in bold.

        All devices tested with iOS 4.3 except where otherwise noted. All results are in seconds. Sunspider is a WebKit JavaScript performance test, with results in seconds. Web Page test measured number of seconds to load www.nytimes.com in its entirety. Don’t be surprised by the faster startup time of the iPad 1 running iOS 4.2; iOS devices without cellular radios have much shorter startup times than those with cellular radios, for whatever reason.
