Apple has no such dominant position in the market, nor has it ever been fined for abusing it.

It's up to lawyers and economists to decide whether the current tablet offerings make up a market in that sense, separate from the cell phone market or the computer market.

Also bear in mind that the case against Microsoft showed a pattern of behavior including its treatment of Java, QuickTime, Borland, and so on.
Next, the only significant platform for browsers was desktop computers. So it wasn't a case of MS owning one category of platform among many. It owned the only game in town.
Further to this, Netscape had been the dominant player on the Windows platform, and Microsoft had undermined it. Apple has closed its platform to rivals who give away their software on other platforms. Apple doesn't stop Google or Yahoo or Bing from making money from advertising on iOS, all it blocks is, essentially, middlemen.
Finally, Netscape was a browser vendor who suffered material damage from having its commercial product undercut by MS bundling policies. No-one sells browsers any more.
Relative merits of two bogus arguments aside... It's pretty easy to argue against. Chrome & Firefox would help security (and this additional consumer choice would probably go well with the pro-market regulators). And they could lift the JIT ban on a per app basis.
The deal with the EU didn't add any choices, it just used Windows to promote alternative browsers to Windows users.
