DervMan’s PDA Requirements

 

M

y core PDA requirements have remained the same over the years; I need a device that can help me organise my work, my website and my writing.  It needs to be portable enough such that I take it pretty much everywhere I go and it needs to have a decent battery performance, so that it works when I have it with me.  You can read how I organise my life using my PDA here.

 

Size and Weight

 

In order for a PDA to be used, it needs to be portable - and this means it needs to fit into pockets, handbags and hands relatively easily.  It isn’t that I have my own handbag but Charlie does and it’s a great way of keeping the device safe!  If the PDA isn’t small enough, it will likely get left behind and thus defeats the point of owning it!  It needs to be light enough such that I don’t feel it dragging me down, too.

 

The best compromise I have is for a device to be “shirt pocket friendly.”  A few devices are small and light enough to be carried about in a shirt top pocket such as the Palm Vx and the m515.  Many modern PDAs are either too heavy or too large to be truly comfortable in this pocket.

 

The larger devices are perhaps suit pocket friendly, which is intrinsically less portable.

 

Battery Performance

 

Once you have a small enough PDA to take with you everywhere, it also needs to have sufficient battery uptime so as to keep working for as long as you need it.  Battery performance is a lengthy subject, which you can read up on here.  The earlier PDAs with their limited processor power and screen technology had a battery life measured in weeks – the Palm IIIxe’s battery life is a claimed two months using Palm’s light use profile.  The Tungsten T3 by way of example has a battery uptime of around three and a half hours.

 

Functionality

 

Finally, once you have a compact enough device with sufficient battery power, it needs to be functional!  This means that the screen must be legible, the device should be easy to operate, it must be stable, reliable and there must be an easy means of getting the information off the device and into the desktop computer.

 

Wireless Email Connectivity

 

This isn’t yet a requirement for my own private device because my work-sponsored unit, well it isn’t mine, I merely use it...

 

The Compromises

 

Of course, there are compromises involved with the three above - what is to one person an acceptable battery performance may be unacceptable to another!  Some people only require the more basic functionality whereas other individuals require all of the bells and whistles.  Some of more dedicated geeks amongst us will put up with a chunky PDA if is has a certain “must have” feature.

 

To a point, the smaller and thinner the device the better.  Of course, the smaller the device, the more compromises that creep into the design - if the device is too small, the screen becomes tiny and difficult to use.  Also, whilst smaller devices use smaller screens with lower power requirements their case designs can only fit smaller batteries.
