To see how these business tablets compare with each other, I used them every day for two weeks in my office and on the road for work. I used each to read ebooks, nose around on the Web, catch up on emails, update a website and give presentations. During downtime, I played a few games and watched online videos. I connected each to my office network, a public Wi-Fi network and a mobile hotspot; I used each tablet's docking station and keyboard; and I made a couple of Skype video calls.
To test the performance of each system, I used PassMark's PerformanceTest 7.0. The software exercises every major component of the system, including processor, hard drive, 2D and 3D graphics and memory; it then compiles the results into a single score that represents its performance potential. I ran the software three times and averaged the results.
I also ran Maxon Cinebench 11.5 to measure graphics and processor performance. The software renders several photorealistic scenes that stress the processor and graphics chip by manipulating up to a million polygons. It reports scores for processor and graphics performance; I averaged the results of three runs.
To measure battery life, I used PassMark's BatteryMon. I fully charged the system and set the power options to keep the system from going to sleep or the screen from dimming. I connected a USB thumb drive containing six videos to the system and set Windows Media Player to shuffle through the videos continuously while the software charted the battery's capacity and recorded the time it shut down. I reported the average of two runs.
Finally, I set each system up with PassMark's BurnIn Test , which runs portions of the Performance benchmark in separate windows continuously, trying to find operational flaws. None were found.
