This is calculated from visits to a  web site.

All the pundits got a big laugh, but the funny name hasn't squelched enthusiasm, adoption of the iPad continues to rise significantly. It'll be very interesting to see when competitive tables come out how they compare.

The BlackBerry Torch hasn't been out long enough to guess whether it matters, but the continued dropping of the BB market share seems an established trend.

What caused the little upward spurt on the iPhone in October?

Symbian has dropped from almost no one to 1 user this month. Are there many Symbian-powered phones that surf the web well?

Mobile usage on membership site, February-June 2010

Each member has an identifiable tag in the log, so if he/she is using an iPhone, iPad, BlackBerry, Android or Symbian device, we count that member ONCE. What jumps out right away is the hockey stick relatively steep rise of the iPad. Next, the BlackBerry lacks growth. Symbian is marginal and Android is growing, although on this site, not many are using it.

Note, I first published a porrly skewed verision of the graph using a type I didn't understand. The above graph gives the proper proportions.

It will be interesting to see if the iPhone rises again with the release of the new generation.

I'm looking at data from server logs from Jan 1, 2009 to Sept 22, 2009 and I was surprised to see these percentages:

iPhone	87
iPod	5
Symbian OS	4
BlackBerry	1
Android	1
PalmOS	1

So in this space, Apple seems to have come a long way from being "Apple Computers" to "Apple" the people who, love them or hate them, invented a very popular new mobile platform.
