Why so many Devices (2):

Today I weighed 223.6, which means I have bounced back up by 1.4 pounds. I think this is a temporary setback; stay tuned...

Two days ago I listed the devices I have that need regular recharging. Yesterday, I implied that some of them should have been replaced by general purpose computers. Let's look at what I think are my exceptions:

Why do I have a feature phone? I could have an iphone instead of the feature phone and the ipod. I think the answer is that the iphone, a general purpose computer (and its smartphone competitors), has not gotten generalized enough. Smartphones are relatively expensive as phones, and many smartphones do not make phone calls very well. Since I do not need all-the-time connectivity, it makes sense for me to have a device that easily makes reliable phone calls, plus the ipod touch. Within a few years, there will be more variety in smartphone pricing, and I will replace these two devices with one.

Why can't the ipod replace my Striiv? In principle I think it can. But the current ipod and iphone may not be good enough yet, at detecting when I take a step and when I climb stairs. That will change too, because better sensory devices in future phones will sell newer games. When smartphones have better sensing abilities, I will choose a "pedometer" app, and my smartphone will have replaced two other devices, the feature phone and the striiv. Oh, and a multitasking OS may be needed to enable "pedometer" apps to work. iOS may be the wrong OS here.

Why can't my iPod replace my old Nokia N800 pda? It can't. That device has a superb spreadsheet interface that is just right for managing a packing list. I have a very long packing list, and I charge the N800 up whenever I need to pack for a trip. My N800 survives because, in effect, it has a highly specialized user interface. (The rest of the N800's UI is disappointing, one reason why the device fell by the wayside.)

Please note that my iPod could attempt to replace my iMac's magic trackpad, but the trackpad holds its own by being inexpensive and very comfy to use.
