    OK, I can't find an answer to this, apologies if it's already been covered:

    I have a non-thunderbolt 27" cinema display bought three weeks before the new one came out:( (no I can't return it:)

    If I buy a new MBA with Thunderbolt, and a 27" Thunderbolt Cinema Display, can I daisy chain the non-TBolt Display as a third screen?

    I.e. MBA > T-Bolt to T-Bolt 27" > displayport-only> non-TBolt 27" ?

    Or is this moot since the T-Bolt MBA doesn't support two external screens anyway?

    I believe it's latter. At most it 'might' mirror the first external-but that's being optimistic. There is no word from Apple that the integrated graphics will support dual screens. Even the 13" pros are out of luck on the dual screen modes.

    New MBAs have a custom Thunderbolt chip and only support one monitor.

    MBAs don't have a "custom" chip. Intel makes two versions, one with two DP lanes, and one with one lane. Airs get the one with one lane because of space constraints.

    the TB spec only specifies two 10 Gb/s lanes, so there is nothing "half" about it.

    It is a moot point. Neither the Intel integrated graphics nor the TB controller on the air support more than 1 external display.
