DigiTimes is reporting -- in its usual sourceless, rumorific way -- that a slew of Taiwanese manufacturers are set to deliver smartbooks based on the Snapdragon and Tegra chipsets by the fourth quarter of this year. Acer is leading the charge with an Android-sporting device, adding to its push of the Google mobile OS, while Mobinnova has confirmed US and European orders for its 8.9-inch élan, shipments of which might top half a million units in 2009. In the meantime, Inventec is expected to launch a 10-inch Tegra smartbook entitled Rainbow, which is probably set for a prompt rebadge. On the other hand, citing what it sees as weak demand, ASUS is holding back and won't launch anything until November at the earliest. While none of these rumors are massively surprising, and given the source could be downright erroneous, they do hint at a wild, industry-wide synergy of smartbook rollout for the holiday period. And we all love synergy.
