I recently acquired an Iphone 5s, 64GB, Verizon phone to replace my old 4s. For years I have been lobbying my firm to let us do corporate e-mail on Iphones (well smartphones generally) and not just Blackberrys. During the week, most of the time my Blackberry sits in my briefcase or on my desk but if I am travelling or on the weekend I should have it in my pocket (hence the annoyance of two devices). In reality, on weekend days where I expect no emergencies I will often just leave it behind although I shouldn't do so. So, I was excited when my firm said we could have e-mail on Iphones. In fact, they are willing to buy everyone either a Samsung S4 or an Iphone 5s (shocked they didn't go for the 5c), but only 16GB. But those will be corporate phones that they will own and effectively control. There is no way I am trading in my personal phone to have only a corporate device notwithstanding cost savings. I asked if I could have e-mail only on my own phone (BYOD policy) at my own expense, but was told no (though strangely this is being permitted with Ipads so long as you agree to wipe them if they get lost). The upshot is that I am stuck using two devices. At first I thought I should get the Galaxy S4 just to have a different device/toy; do I really need two Iphones? OTOH, there might be times when I really don't want to carry two devices and with a work Iphone would have the option of carrying that one and still having Iphone functionality, which I like. Also, I just prefer the Iphone form factor better, although the S4 seems like a perfectly excellent device (Android has come a long way from what I can tell). Any thoughts are appreciated.
