According to a report on Wednesday from industry watcher DigiTimes, Acer is seeing higher than expected interest in its upcoming line of tablets. Demand is so high, the report claims, that it exceeds the initial supply Acer has ordered from its manufacturing partners. The strong demand comes from various cellular carriers around the world that are seemingly eager to bundle Acer’s upcoming devices with data plans. According to the report, Acer plans to launch four devices between now and April: The 10-inch Windows 7-powered Iconia W500, which will launch mid-March; the 10-inch Tegra 2-equipped Iconia A500, which will run Android 3.0 (Honeycomb) when it launches in late March; the 7-inch Android-powered Iconia A100, which will launch in April; and the supersized 4.8-inch Gingerbread smartphone dubbed Iconia Smart, which will also launch in April. Acer noted that initial limited inventory  is due to a short supply of key components, such as touchscreen displays.
