Shipments of Asustek’s popular Eee Pad Transformer tablet have surpassed 400,000 units per month according to a report from DigiTimes. The industry watcher cites anonymous sources at touchscreen display panel suppliers in claiming shipments are expected to grow even further in the third quarter, possibly reaching up to 500,000 units per month. ASUS reportedly hopes to ship between 4 million and 5 million tablets across all of its models during the second half of 2011, and almost 3 million units could be Transformers if DigiTimes’ report is accurate. Analysts at J.P. Morgan Chase claimed last month that sales were slowing and ASUS’ convertible tablet was overstocked in some channels, but this continued high production volume would certainly suggest that the opposite is in fact the case. The Eee Pad Transformer is a 10.1-inch Android 3.1 Honeycomb tablet with a dual-core Tegra 2 processor that ships with a full notebook-sized keyboard dock. The slate can be used on its own or docked so that its function more closely resembles that of a laptop computer.
