In an interview with Pocket-Lint, Sony Ericsson's global head of marketing, Steve Walker, acknowledged that they had made some mistakes in 2010, but have changed their focus somewhat and learned "a huge amount last year." One of the areas that Mr. Walker acknowledged they would improve on is the timeliness of Android updates onto their devices.
In the interview, Steve Walker mentions that in 2010, hardware was a lower priority for them than software. However, he meant Sony Ericsson's Timescape software, and not Android OS updates. In addition, they did not correctly predict the direction the smartphone market progressed in.
Many Xperia users last year were upset with Sony Ericsson continual delay in pushing out the Android 2.1 update to the Xperia line. In addition, it appears that Sony Ericsson revealed to an Android blog in early January that the Xperia X10 and X8 line will not receive an official Android update past 2.1, which doesn't seem to me like they have changed their stance in regarding how important Android updates are to users.
He also mentioned that in the coming year, hardware and software will be more balanced in regards to priority. As if to prove that, he pointed to the Sony Ericsson Xperia Arc, their new flagship Android device, which should go on sale in a few months.
Much to the chagrin of Sony Ericsson Xperia users frustrated with still being stuck on Android 2.1, Mr. Walker said that "'If we hadn’t done what we did with the X10 and the X10 minis we wouldn’t have been able to do what we’ve done here today” as he looked at the latest Sony Ericsson handset, the Xperia Arc, with a smile on his face.
