How about this:
iSync for managing everything between iDevices (apps, music, movies, books, etc)
iTunes for managing, playing, and editing music. Get rid of GarageBand.
iMovie for managing, playing, and editing video. Get rid of QuickTime and iDVD.
iPhoto for managing, viewing, and editing photos.
iChat for all person-to-person communication, including text and video. Get rid of Facetime.
iWeb for creating and browsing Web sites. Get rid of Safari.
App Store for downloading and managing apps for both iOS and OS X.
Pages for creating, reading, and editing Word documents and PDFs. Get rid of Preview.
Numbers for creating, reading, and editing Excel documents.
Keynote for creating, viewing, and editing slideshows.
Include Pages, Numbers, and Keynote on every new Mac, just like iLife.
While music, videos, apps, photos, PDFs, Word documents, etc can be used by other apps (such as iSync), everything would be manipulated only through their respective apps.
That could work. I don't care what they do, so long as it's clean and simple and make the apps much snappier. iTunes is bloated and slow, even on a mac. Even 'pages' and 'final cut' takes less time to load than iTunes. iTunes should be for managing and editing SOUND files only. It doesn't deserve the iTunes name now, because it now has apps, movies books, etc... ridiculous.
iTunes should be music, audiobooks, ringtones, and radio only, NOTHING ELSE!!!
here's what I think...
iLife
iTunes: Manage, play, edit all sound files. Merge with garageband.
iMovie: Manage, play, edit all movie files. Merge with quicktime, iDVD and DVD player.
iPhoto: Manage, view, edit all image files.
iWeb: Edit, manage websites.
What about logic, final cut and aperture? Well, have them as separate apps, which are more powerful than the iLife apps, however how to organize it AND the iLife suite's library to be the same? Mirror it. e.g. iMovie and Final Cut library are both the same. When you make a change to the library in final cut, when you later open iMovie, it instantly feeds that info back to the iMovie library so it's in perfect sync (Is this even possible, lol). I personally hate having two libraries for iPhoto and Aperture. ugh.
iWork
Pages: Manage, view, edit all pages/word/pdf files. Includes iBooks.
Numbers: Manage, view, edit all numbers/excel files.
Keynote: Manage, view, edit all keynote/powerpoint files.
iWork is free on all new macs, however there is a $29 upgrade each year.
That way they can remove textedit and preview and not having to worry about not having pages to view these files.
Standard apps
Finder: Well........ finder!
iChat: Text, video communication, blogging and incorporate ping, twitter and facebook features in. Remove the facetime name and incorporate Photo Booth.
Safari: Browse websites and manage feeds.
Mail: Incorporate iCal, address book, mail and stickies. iCal and Address book are configured in their own app, but can be viewed directly in mail without having to open separate apps. Also allows to manage feeds etc... (sends info back/forth to safari) and allows for multiple mail clients on the same system.
Calendar: Rename it from iCal to calendar. Have mail be able to read/view Calendar info, but can only be edited through the calendar app itself.
Address book: Same as above. Mail can read/view address book info, but have to be edited through address book.
Calculator: build calculator into iWork suite, but have separate calculator too.
Preview: Keep preview. It can open ANY file and play it/view it directly. Make small adjustments to films and photos or documents to save resources.
iStore: Manage, purchase and download/downloaded apps, music, movies, books etc... for iOS and OSX.
iSync: Most important in my opinion. Manage/sync any data on your mac with any connected devices (that support them of course). Cameras, phones, sd cards, iPhone, iPod, iPad etc... Merge with image capture and allow for all i-devices to be used as external storage devices.
All in all, I just think we need more choice of what apps we sometimes use to do what things. I sometimes get sick of reading feeds in my tiny mail window. Sometimes, some feeds have large images in them. So I'd rather view/manage those feeds in safari instead. That would be cool, so if I had read a feed for example, it would just send that info back to mail, so I don't read that feed twice. Also, sometimes if I want to send an email to a friend to make plans, but forgot his email and am not sure if I am free today according to my calendar, It would be nice to have an address book and calendar app built in to mail, without having to open up each app just to see that info.
There are lots of other scenarios where this can be incorporated too. Just makes life easier.
Just my 2 cents. Cheers
