A slow start doesn't necessarily imply doom ... but, for comparison, Apple sold 300,000 iPads in its first three days. Motorala Xoom has sold 100,000 in its first 40-some days.
The tablet battle really has yet to engage. With Apple staked to a 20-million-unit lead, they own the conversation (and market) for the forseeable future.
One Deutsche Bank analyst used the Android developer site to gauge interest in the Xoom, according to Silicon Alley.
If an Android-enabled device like Xoom is stumbling out of the gate, can RIM's tablet reception be any warmer? That depends on how they leverage their reputation for business security.
