Apple (AAPL) devices figured prominently in an IBM (IBM) Smarter Commerce survey issued Saturday that reported double digit increases in online sales Thanksgiving Day (up 39.3% from 2010) and Black Friday (up 24.3%) and a 200% increase in purchases made on mobile devices (from 3.2% in 2010 to 9.8% this year).

In particular: (I quote)

The Apple Shopper: Mobile shopping was led by Apple, with the iPhone and iPad ranking one and two for consumers shopping on mobile devices (5.4% and 4.8% respectively). Android came in third at 4.1%. Collectively iPhone and iPad accounted for 10.2% of all online retail traffic on Black Friday.
The iPad Factor: Shoppers using the iPad led to more retail purchases more often per visit than other mobile devices with conversion rates reaching 4.6% compared to 2.8% for overall mobile devices.
Surgical Shopping Goes Mobile: Mobile shoppers demonstrated a laser focus that surpassed that of other online shoppers with a 41.3% bounce rate on mobile devices versus online shopping rates of 33.1%.

The relatively weak showing by devices running Google’s (GOOG) Android, despite a market share that dwarf’s Apple’s iOS, is consistent with earlier studies that found Android users spending less time online and far less money on apps.
