A recent survey of 4,028 US consumers by ChangeWave has thrown up a number of illuminating statistics, which you might consider as predictable as they are informative. The chief takeaway is that people are keen on buying smartphones like never before, with 16% of respondents saying that they'll be taking the plunge within the next 90 days, which marks the biggest increase in the survey's history. Secondly, and crucially for vendor loyalists, Apple and HTC seem to be the biggest beneficiaries (or are they the stimulants?) of this interest, with both improving their share by over 50 percent between March and June of this year. RIM and Motorola have taken a tumble in that same timespan, while Palm has sadly failed to register even a single percentage point. We can definitely see the Droid X and BlackBerry 6 remedying things for the big boys, but Palm's route out of ignominy seems a little less straightforward. You'll find a chart of customer satisfaction -- dominated by Apple in imperious fashion -- after the break, and the full breakdown at the source link.
