nokia 5800

5800买回来后就一直当“电话”和“地图”使，实在是一种浪费

于是乎，开始google—— 我可以在5800上面安装另一个操作系统？

nokia官方论坛上8月份的一场讨论 提醒了我：不要幻想5800某一天会变成macbook

安装在N900 上的 Maemo 虽然更适合触摸屏的nokia，但是并不意味着你可以在5800上面安装它。

The 5800 is based on ARM11 and uses the ARM 6 instruction set. The N900 uses ARM Cortex-8 which uses the ARM 7 instruction set. So maemo will not run on a 5800 or actually any other device that does not run ARM 7 architecure.

linux is pretty adapable to all processors is often what is used initially for processor development. But linux is not an embedded operating system so you need to develop a CMOS, drivers for all your input and output and wire it all up and you would have it.

你可以把N900当作一个 具有手机功能的电脑 ，但是，5800只能算是一个 具有多媒体功能的手机 。

现实一点吧：

Generally mobile phone manufacturers do not rush to make driver-level details available for everyone. I would guess that this particularly applies to flagship devices.
For this problem, there would be two 'solutions'
1) someone reverse engineers the device, and makes linux /Maemo available - it is illegal, but not impossible after all. Takes some time of course, but it is the time of whoever does it - feel free to do that if you want
2) Nokia does it: it would certainly succeed, then
- Nokia would have to provide end-user support for it ('how to change background image on 5800 S60', 'how to change background image on 5800 Maemo' would be two distinct questions)
- Nokia would have to provide developer support for it, because the device itself would still differ a lot from other Maemo devices - I guess you would not want to give up the phone functionality in favour of having a linux kernel
- applications released for 'the 5800' would turn out to be incompatible with 'the 5800', because there would be no such thing as 'the 5800' any more. Possible result: "Bah, 5800 is crap, I tell it everyone, upload to YouTube and write on my blog, then I buy something else"
- Nokia could try providing everything from its own side to be available on both OS-s, which would be possible, but obviously require resources (time, manpower)
- doing the port itself also requires resources
- product life-cycle of nowadays mobile devices is relatively short ('consumerism', 'throw-away society', and the like), so all of these efforts would be spent on a device which has already passed 20-30% of its lifetime
Exactly which of these factors should make the idea attractive to Nokia? The idea of making a successful product potentially less successful at the cost of spending resources on it. In my opinion "real" "XpressMusic people" do not want to change the OS. And if they happen to change it, they will not understand why things (from 3rd parties) start malfunctioning.
