When I complained to Nokia last March about the lack of support for the Meamo OS and we were not getting Nokia supported meego, just after I got my device, I was told the following in an email:-

"As to you question: my understanding is that Meego will be a replacement platform that will be launched in future devices. The MeeGo is using a different hardware platform (Intel based x86 instead of the ARM) and thus it will not be compatible with the N900 device. However N900 will keep on receiving upgrades and is supported by Nokia."

I assumed at the time this person replying on behalf of Nokia had got thing wrongs but given the latest rumours perhaps the y were in fact correct??
