Yeah, I see what you did there: you applied something I said about software on embedded hardware.

What I said about software applies even more on embedded software than desktop software because of limited resources.

In hardware is much more limited. Especially embedded hardware. Modularity comes at price of more power usage and more size used. Same for features. I'd also love to have dual SIM, for example, or be able to replace the WLAN later with 802.11n, but that is not possible either.

Question is also which interface you'd have that modular cell transceiver. I think we discussed the options before: there is no suitable one for handhelds for end users while on x86 hardware from netbooks and up you can have MiniPCI Express.

That is why Apple solders their stuff, and does not allow user to replace. The side effect is ofcourse you are dependent on them and have to upgrade whole hardware. Well, Nokia benefits from such side effect too. Else we'd just upgrade our phones ourselves the whole time.
