Really, what was your point again?
Your argument is invalid.
In reality, it's somewhere between feature and bug. It means the manufacturers can make a large number of different phones without a Legion of employees to keep them all up to date and it gives customers choice in both hardware and os. It kinda pushes people to be involved with their phone and to start hacking on their phones. Having said that, it's annoying when you outgrow the capabilities of your cheap phone before you're eligible for an upgrade.
