All signs suggest tablets were very popular Christmas presents this year. Analytics firm Flurry claims tablets made up 51% of all iOS (AAPL) and Android (GOOG) device activations it detected on Dec. 25, compared with just 20% from Dec. 1-20. In total, Flurry detected 17.4M Christmas activations, up over 2.5x from 2011's 6.8M. One caveat: Flurry relies on data shared by its huge app network to determine activations. Hence its numbers could be affected by download activity and changes in the size of the network. (IDC forecasts)
