There are a number non-interoperable solutions today; PayPal, Amazon Payments, Flattr, Google Checkout, Ven, Bitcoin, BankSimple, Square, and KickStarter are a few examples
Yes, I know that it is completely off-topic, and I don't usually comment on people's signatures, but yours got me intrigued. Can you at least tell me who they were playing against?
There's actually quite a market for tablets, in case you haven't noticed.
But it would be a mistake to use the same UI which was designed for use by a mouse as a touch-screen UI. If a user interacts with the UI using the touch screen, UI elements like menus should be larger and behave differently than when they are accessed with a mouse. For example, scrolling a page could be a swipe on the screen, but using a mouse a swipe would be awkward. Specifically, the mouse paradigm where you move a little pointer on the screen and press a button must not be copied to the touch-screen paradigm, such that pressing a finger on the screen is equivalent for the OS a mouse-button press. Such an implementation would be disastrous. Instead, the UI should adapt to larger fingers, be less picky on where someone lands his fingers, and use larger, dynamically appearing GUI elements so users can see what they are doing, as their hand and fingers are now in front of the screen. And use swipe gestures. Lots.
I think laptops with touch screens are the future, but I suppose it will take some iterations before Microsoft and Apple understand the differences and optimize their GUIs for use by touch screen as input device. In the mean time, creating a single UI for both mouse and touch-screen input is plain dumb and a waste of effort.
Better anticipate on the things you want to do on Mars, than to send over raw materials and a 3D printer, and think... "gosh, what shall we put together today?"
I get it. In the name of fighting terrorism and now GW, the people are stripped from their civil rights, liberties reduced and taxes increased.
Just as with religion, GW and terrorism are represented as a great threat and oppressive measures follow soon after.
This is a time in history to start paying attention.
Which ones, old, pre-retina iPad apps or newer retina iPad apps that will look like shit if they work at all?
This device should have had a retina resolution if it was to exist at all. Now it is just an enlarged iPhone. Only few developers will target this device specifically. It will be a niche device. I can see it being used by waiters for taking orders on a busy terrace. But as a media consumer or internet front-end device it will fail. The screen is a huge step back compared to all other iOS devices except the iPad 2. If Apple really believed in a device of this size, it should have had a retina resolution.
Apple should have kept the retina resolution. Sure, the display would be new in terms of number of pixels, but at least the number of ppi would be more consistent. Everything would appear comparable in size. Now, on the iPad mini, everything will seem larger while at the same time the display is smaller than an iPad.
This will just not fly. Developers will be reluctant to adapt their apps for this device. Lack of apps will result in low sales. This device will FAIL.
