> The question I have is, should OS GUI's be 100% web based, only providing the building blocks for running browser windows in effect. If you ask me: No. They should be 0% web based. Browsers are the worst platform for GUIs that has ever been devised. You will probably even get better OS integration if you write your GUI in Squeak or Oberon. Quick checklist for high quality GUI applications: [ ] Does your application allow arbitrary shortcut keys with and without command keys that are user definable? [ ] Does your application use the correct OS-provided system paths for user documents, preferences, temporary files, etc.? [ ] Does your application have the look and feel of other applications on the OS and does adhere to the OS developers user interface guidelines? [ ] Does your application work exactly the same on every platform, except for platform differences like command keys and menu positions that are expected and desirable? [ ] Does your application provide instant user feedback when the user operates controls, click with the mouse, etc.? [ ] Does your application allow drag & drop to and from the desktop on OSs that support it? [ ] Does your application work offline as well as online and allow the user to export and backup all data stored by the application to arbitrary locations? [ ] Does your application work gracefully with nonstandard or slightly outdated filesystems? [ ] Does your application respect file permissions and other access control features of all platforms? [ ] Does your application use controls that are appropriate for the data and do these work seamlessly with huge amounts of data such as lists of millions of entries? [ ] Does your application keep confidential user data local or does it protect this data with strong encryption and user-supplied keys if it stores data online? [ ] Does your application have unlimited undo? [ ] Does your application estimate the time of long operations correctly and always displays a time estimate and progress without blocking the GUI when an operation takes longer than a few seconds? [ ] Does your application highlight user selections and allow copy & paste to other applications running on the user's machine? [ ] Does your application use the standard system fonts or does it have a good justification for not using them? [ ] Does your application otherwise integrate well into the OS environment (e.g. desktop), for example by updating a tray icon, providing OS level notifications, linking up with OS level backup and indexing services? If the answer is NO to any of these questions, then your application sucks. I might have forgotten some, tough.
