Everyone, are we actually talking about "multitasking" ? or "fast app switching with saved state" ?
Because the definition of multitask is doing multiple tasks at once. The One X clearly does this if you look at the Running Services tab. I can be playing music, load a video game, get a text message(via SMS Popup), quick reply to the text(again using SMS Popup), go back to playing the game(it never exits the game, SMS Popup appears ontop of the game) all while the music continues to play. By this very explanation, the One X multitasks fine.
What we should really be calling this issue on the One X is that it doesn't fast app switch with saved state. I can't play a video game, exit the game, go to messaging, respond to a text, and go back to the game and expect it to be at my saved state.
Is this a Sense issue or a Google issue?
