Windows/Mac: Search is a feature that's been oddly missing from Google's Android Market since its inception, though it's due to arrive — along with over-the-air syncing — very soon. In the meantime, doubleTwist continues to bolster its Android offerings with a built-in Market search.
It seems like doubleTwist is truly set on living up to its unofficial nickname of "iTunes for Android". While you still can't install or sync applications from the Android Market to your phone, doubleTwist does provide the now-standard QR barcodes for easy scan-and-install searches. The search works fairly well, and sitting next to the Amazon MP3 Store and a powerful podcast search app, it makes doubleTwist a powerful syncing utility for wielders of any Android phone. Someday soon, we'll have remotely synced music, photos and apps, but in the meantime, there's doubleTwist.
doubleTwist is a free download for Windows and Mac,
though the Market search appears to be a Windows-only update at this point.
