A new estimate today has shown that iPad pre-orders are still on track to beat the iPhone's initial launch numbers. With advance orders believed to have hit 190,000 last week, the rate of purchases has slowed down but should still have reached 240,000 of the tablets as of Friday. The current average of about 7,000 pre-orders per day would have the iPad beat the 2007 iPhone's 270,000 launch weekend units by Monday based purely on online sales.
