Nearly twice as many Canadian CPAs and CPA students use an Android smartphone (59%) as an iPhone (34%), according to our latest reader poll. The Android is the most-used phone among respondents in all age groups and regions, except for those who work in public practice, where half use an iPhone and one-third use an Android. Just 8% overall use a BlackBerry, although that jumps to 22% for respondents between the ages of 40 and 54. Most of you say your smartphone is primarily for personal use (64%), while 31% use it equally for both work and personal reasons. As for phone size, 75% of respondents under 30 use an extra-large smartphone (5.5 inches or larger), compared with just 36% overall.
