I disagree - if you can afford to use them only with your computer (and you can find them) get 1's. There's no nois and the DAC issue is moot - there's no analogue in your computer anyway. The DAC's on Macs aren't trash but that doesn't make them good. The DAC's on the soundsticks are very well matched.
The lack of noise is a huge advantage. Directionality isn't an issue (they're for a single user - not a room. Bass is great and reasonably tight - not bloated (like most computer speakers). Not deep (though that's more usual than not - few computer subs get below 30-40Hz)
Finally the 1's were a more expensive item and are not loaded with blue rubber rings. The 2's are - IMHO - watered down. They look like soundsticks but are in fack just very expensive regular speakers. The 1's are inovative, pure, uncompromised and classic.
you can't go badly wrong with either but I'd take the 1's any day, no question.
