Lack of freedom online is not a good thing.
Commonly multimedia is a part of my daily life and day to day activities, and without it things would seem pretty boring or dull.
Most webforms online I fill out are Flash based and without Flash I would not see these websites as they were intended to be seen as the developers made them for site visitors to see them.
And as a developer, I tend to use Flash for key areas in network development, graphics, interacivity and dynamic data management with or without connectivity.
From a graphics standpoint:
Flash has moved forward into the 3D rendering realm and games such as Interstellar Marines is a good example: http://www.interstellarmarines.com
A good representation for it's 3D is in it's development which is highly simplified but similiar coding sytanx and names as DirectX and OpenGL, with hardware acceleration options, which make it very powerful, especially given the fact all this can be done in a browser or application locally or remotely. Even audio is good and streamed video playback.
Sites like YouTube enable fast streamed video and audio with Hi-Def playback options now. Especially sites such as Hulu.
Alternative Flash Controllability:
Touch and Wii Remote options do exist, even WiiFlash on TV and to control on screen projector presentations.
From a realistic standpoint, most websites these days use Flash, I spend some time each day watching videos, movies, and shows, mostly through Hulu for Movies and TV Shows, and Youtube for information.
The least Apple could do is provide the option to turn Flash on or off, and keep it simple, so everyone is happy and satisfied with the product, if you want to turn it on then turn it on, if you don't want it on the turn it off, simple.
Personally, I want and need it on or else I'm going to have to spend time figuring how to develop custom app's and solutions to get by most the issues I'm facing with lack of Flash support on this device and I'd really rather be spending time working on the projects I'm already working on and not that.
While I can see some security and performance points, I'm not totally sold on the Flash solely uses so much more battery power than anything else thing, except when dealing with the devices screen being on and processor being used more, and if that is the issue then the hardware design needs improved to deal more intense applications, just like with the battery and charging systems, after all this is what they are is a hardware and software developer, and since they own the technologies they develop might as well spend time making solutions and not excuses to why their hardware doesn't support it.
It's a new start for them so I hope to see these touch devices evolve over time and not be lacking in features people really want and need to use each day, I don't need another newspaper reader or portable mp3/video player, picture viewer, calender, calculator, or simple organizer. I need powerful touch screen webbrowser with wireless networking using the full Wireless N spec and freedom to move around and touch the screen to interact with and manage data. Watch movies and videos and listen to music online through the handheld device, as well as remote desktop and online file host management with atleast 25GB online storage capacity like Skydrive and remote capability such as Live Mesh.
I used to be able to do simliar with Pocket PC back in 2002 on an Axim X50v and Windows Mobile 6.5, until the wireless stopped working. And Windows Mobile 7 will not run 6.x code. It is based on Silverlight and .Net. Everything except a few basic programs will not work under Windows Mobile 7. The focus is currently on games including some XBox Live functionality for gaming and messaging. There will be a Microsoft App store with an easy approval process.
But I really want to see Flash support in the iPhone/iTouch/iPad with ability to turn it on and off and no jail breaking required to make it do things it should already do.
