Verizon Wireless is working with Google to develop a tablet computer that would compete directly with the iPad. The Wall Street Journal reports that the development was confirmed by Verizon Wireless CEO Lowell McAdam, who declined to discuss details on the timing or manufacturer of such a device. “What do we think the next big wave of opportunities are?” Mr. McAdam said in an interview. “We’re working on tablets together, for example. We’re looking at all the things Google has in its archives that we could put on a tablet to make it a great experience.” Google declined to comment on the WSJ article, apart from saying that anyone can use its mobile software to create phones and other devices.
