why is it concern you as a user? Unless you are an android programmer. And if the update rolling out slower, it does not make the phone value depreciate slower.

For me, the real value of the phone is its build quality and usability. Build quality can determine how long you will be using it, the better the build quality, the longer you can use it, and more value it will bring to you. The usability of course is the usefulness and function of the phone that can help/entertain you in your daily life.

My previous Treo 680 has been serving me for 3 years plus and i must say it is an excellent phone, but due to normal wear and tear, the phone function has some problem recently. So I upgraded to Desire. In the aspect of usability, the only "upgrade" for me is the Wi-Fi connectivity on Desire coz the Treo 680 does not have it to check my office email. All the other features of Desire - AMOLED screen, fast hardware, lots of softwares to choose from, etc are just the icing on the cake.

That's why I choose my next phone carefully, after research high and low and finally settle on HTC Desire. I believe it will serve me for quite some time. If there is free update in the OS - Froyo/Gingerbread/whatever, I will appreciate it but if not, I just utilise whatever I have.
