If you think of Second Life as a game, then its a given that SL Residents are probably playing other games, too. Except for Solitaire, almost all my gaming is off the desktop computer and on my iPad. Lately, when I can get my hands on the iPad (we really need a third one in our house) I've been playing Words With Friends with my SL wife, Angela, and playing LEGO Harry Potter: Years 5-7.
It has also come to my attention that except for Second Life, everything I do on the desktop computer can just as easily be done on the iPad. In fact, if it weren't for Second Life, I probably wouldn't need the image editing software I own or the system maintenance software I've purchased or the desk and chair that make my bedroom oh-so crowded. All the Web browsing I do is often more easily done on the iPad, the one desktop game I play is also on the iPad — Full Deck Solitaire. I could even ditch Blogger and use Word Press for my blog.
Additionally, most of the games that I play on the iPad are far more expensive if purchased for the desktop, if they are available. The Harry Potter game, for example is $4.99 USD for the iPad while the desktop version is $29.99 USD. Sure, there are differences. The latter one is far richer in graphics and gives more options, but weigh that against being able to sit in the living room or kitchen or even the back deck while playing and I think the iPad version is a bigger WIN.
So why isn't Second Life on the iPad yet? The click-to-navigate viewer interface works. Various windows like the Inventory could be tweaked to allow easier tap-to-use access. Saved outfits makes changing clothes or whole avatars speedy and easy without having to use your Inventory. And the attach-on-demand HUDs feature (used for Linden Realms) would be a huge boon to making "Tablet Life" much easier.
Doesn't The Lab want Second Life to be a social platform anyway? What could be more social than being able to easily take The Grid with you from room to room in your house or place to place in your travels? And here is how they should start: Create a mobile app for using the My Second Life Feed/Notifications features. Then residents wouldn't need to use Twitter (I don't) or Plurk (my account is on 'vacation') or other services to talk about SL. The middle man is out of the picture. Then I could be running around as the adorable Ginny Weasley in the Harry Potter game and quickly four-finger swipe to the My Second Life app to respond to a notification that someone has messaged me.
