1.) I never stated that the Skype on the DSi would have an impact on the iPhone.
2.) As far as the success of gaming on the iPhone, last I heard it's quickly become a haven of shovelware.
Yes the iPhone is a powerful all-in-one portable device. Yes I can see the benefits of that. No I don't think that makes it the golden bullet portable gaming revolution that the Wall Street Journal would like to think it is, because the fact remains that the people in the gaming industry who get paid to make the type of games that actually turn significant profits don't see it that way. I'm sorry, they don't! Want proof? Name three game development companies that make iPhone versions of their main franchises in-house. Off the top of my head, I can only think of two; ID Software who last I heard had plans for Quake on the iPhone, and Pop-Cap Games, who only make the snack-size time wasters that thrive on the iPhone anyway. Damn near every other game developer licenses out their properties to a third-party, who in turn tend to make lackluster mobile versions of these franchises that are quickly forgotten in a week. Does that mean that the iPhone can never compete in the handheld market? No, it doesn't. Does that mean that cell phones can never join in the handheld market? No, it doesn't. It does mean however that they aren't anywhere close to being actually competitive.
You want the gaming community to take the iPhone seriously, you are going to need to show a game that's more worthwhile than the 5 minutes you fiddle with Lemonade Tycoon at the bus stop. The iPhone NEEDS a game with the same type of impact and gameplay quality as something like Mario Kart, Final Fantasy Tactics, Sonic the Hedgehog, so on and so on. iPhone games are still in the Peggle era right now. You want to compete with the handheld gaming industry, as opposed to the shovelware festival that is the iPhone app store, then you need to be holding yourself to the same standards as Nintendo, Sony, and those developers who make the grade A titles that define the experiences for the DS and the PSP.
Simply having a ton of snack-size freeware games doesn't cut it.
