When the rumours of multi-tasking were doing the rounds this week, I always said I never expected to be multi-tasking on my iPhone 3G, it simply doesn't have the memory.
However, it would have been a bit less of a blow had Jobs said from the outset that it would be a 3GS feature only ... demoing it then telling us right at the end that it wouldn't happen on a 3G was like saying, "Look at all this new stuff" then sticking the finger up at us.
Ah well, nothing that wasn't expected ... but the execution could have been better.
