It'll be an extremely small minority that legitimately stops buying Apple products because of this. What will happen though, is further escalation of the patent wars. Is the backlash from this recent trial going to weigh on the jury for the four patents Apple's trying to assert against the GSIII and the newer devices? No clue.

However, from what I've seen in early discussions regarding Samsung's LTE patents... they may have a stronger position there than the FRAND patents they were trying to claim against Apple in this most recent case.

Samsung killing agreement with Qualcomm to not sue their customers once Apple took the Galaxy Tab to court:

These specifically involved 3G patents, but it's not a stretch to think that this will extend to any 4G patents, especially considering recent events.

On top of that, the LTE patents Samsung could assert against Apple are considered "seminal" patents, not FRAND:

"Unlike essential patents, which are declared by companies (primarily larger firms) on standards such as ETSI, IEEE, etc, seminal patents are a set of strong and significant patents (‘STAR’ patents) identified from the entire portfolio. These are selected based on 22 parameters such as infringement detectability, number of independent and dependent claims, technology activity rate, backward and forward references, age of patent, etc. A seminal patent list helps identify other strong patents in the 4G-LTE landscape and their assignees – patents primarily belonging to SMEs and NPEs."

Per that doc, Samsung is also the holder with the most LTE patents with 9.3% of the total LTE patents.
