Mobile computing devices AKA

As phones generate curious behaviour.

For example, the standard 'keyboard' generally works well, yet there are dozens of alternatives that look a little different for which one must pay, in cash and in giving access to personal data. Why would anyone give access to their contacts and personal data, just to use something that does the same thing s with a slightly different look?

That was the first example that sprang to mind, but there's plenty of others.

I really don't get the lemming-like rush for more and more apps that do what is already being done with no more than cosmetics as a USP. Blackberry and Windows phones are shunned because they lack a large app store - weird - even though many of the key apps are available for those devices.

Please explain this to me, if you can.
