Mobile Lowdown 6-28-11: Apple/Samsung; Microsoft/Android; Skype; TouchPad

A look at some of the big stories in mobile today:

Samsung/Apple: Looks like the two companies’ legal disputes over trademarks, patents and copying are spilling over into the other key area where Apple (NSDQ: AAPL) and Samsung meet…as customer and supplier. This report says that Apple is considering using Taiwan Semiconductor Manufacturing Company to supply it with A6 processors in 2012, a contract that currently goes to Samsung. The A6 chip is used in the iPad tablet.

Microsoft/Android: Redmond has signed a patent licensing deal with General Dynamics Itronix, covering its rugged tablets and other devices based on Google’s Android OS. Microsoft, which claims that Android violates Microsoft patents, has signed on a number of other device makers including HTC. (via Microsoft)

Open and closed Apple: Is Apple in trouble in the long run because of its closed system? NBC’s Paul Hochman, speaking at a Ford Innovation event, thinks so. (via Pocket Lint)

Skype: More allegations about what is and isn’t going into executives’ packages as they depart from Skype in the lead-up to its acquisition by Microsoft (NSDQ: MSFT). (via Reuters)

TouchPad: HP (NYSE: HPQ) makes the case (again) for why its tablet has a good fighting chance in the tablet market. The bottom lines are its web compatibility and the fact that the market is still largely untapped. (via Fast Company)

Opera: 200 million users are now on the mobile-friendly browser. (via TechCrunch)

Tom Tom: Are the tom-toms sounding for Tom Tom? The GPS navigation company has cut its sales forecast once more, an indication of the impact that competitors from both the GPS and smartphone spaces are having on that market. (via WSJ)
