• netTunes This claims to not support Leopard on their home page, and they are not joking. Basically it seems to do some kind of remote VNC type of solution, so you might as well just use Leopard screen sharing.
• TuneConnect  - This one looks really nice, and you get a nice full interactive view of available playlists. There is a search feature... however when you double click on a song it plays that song... but doesn't continue playing all songs in the playlist. You can "add to party shuffle", which is useless as it them automatically gets shuffled. So no use whatsoever.
• iTRC - This one is very simple and cut down, and in fact in an effort to keep the app from using up too much screen space, they made it so that you can't resize which is a pain. You need to make sure that you get the more recent 1.4 release. Don't get it confused with "Remote Itunes" from "Delicious". This has a search facility, which actually works, and remotely generates a new playlist on your real library. This is then automatically played, and it also plays more than one track. However... note that the new playlist will have some kind of ordering in your main iTunes library. Go to that machine, and ensure that the playlist is sorted by the "track number" column. That will ensure that the tracks of an album are played in the correct order. And even when a new list is generated the next time you search, it will retain this sort criteria. This means of course that if you want a different ordering, you have to go to the other machine again (defeating the point somewhat). However... and here's the real gotcha. Every time you launch it, it forgets the user name and password for logging into the server. That is a showstopper. All it needs is this little fix...
• Remotes iTunes - looks just like itrc (they even reverse their own application name between the menu and the title bar), but is actually different, and doesn't have the remote search playlist feature. The search that it does provide suffers from the same problem as TubeConnect, in that it only allows you to play one track at a time.
• Signal - Not actually a native app this time, but it's the only one that actually works! It provides a simulated iPhone web app interface on a desktop browser (and presumably an actual iPhone web app experience on an iPhone / iPod touch). It connects quickly and seamlessly, and provides all the native features as found on the iPhone music player app. $25.

Lux free open framework enables true multitouch interaction in Mac OS X. In fact, he says it can work under any platform and even a web browser, enabling complex user interfaces and object manipulation...

...the battery swap should take no longer than it would to fill a tank of petrol - but he claims 20 seconds is do-able. Drivers won't own the batteries, and will pay based on miles driven rather directly for electricity used, so the age of the battery installed shouldn't be a major issue so long as it's good for the specified mileage, nor will drivers lose money by trading in batteries before they're fully run down.

Microsoft could use Flickr's library of images, perhaps the largest library or organized and categorized imagery in the world, to advance their research with their HD View research. HD View is emerging technology being worked on at Microsoft that allows impressive panoramas to be created by stitching photos together. By combining mapping and geotagging, Microsoft could look to create new ways for collaboration to take place by merging Flickr photos together.

• the 10-foot menus are now shown over the top of the playing program now, so you can navigate around without missing the action
• you can't invoke the 10-foot menus using the mouse now, you have to right click or press Option-Escape.
• the channel list that shows now/next seems handy
• smart playlists are very handy, for example to make genre playlists or films by searching for duration over an hour, for example
• smart guides are excellent as you have full control of adding boolean search terms, you can auto-add to playlists, and you can keep up to a certain number of episodes (i.e. the only way to do an auto-delete type operation)
• there would be one additional feature that would make it complete... you need to be able to say "please don't record two programmes in this smart guide that both happen to have the same episode id"
• let's hope it's more stable!
  

Imagine if it charged the MacBook wirelessly as well, using inductive coupling like an electric toothbrush. Cables and sockets could be eliminated altogether.

• installation (upgrade in place) was smooth and flawless. i took care to disconnect my bootable backup disk, but had no need for it.
• partitioned my backup disk into two halves, one for timemachine and one for aperture vaults. this seems to work fine.
  
• app startup does feel quite snappy, overall performance not convinced that i can tell any differences.
• spaces are more stable than virtue desktops, but the animation between spaces stalls horribly every time - when virtue was smooth as silk. however, one difference is that virtue used to slide the whole desktop including the background, whilst spaces moves the apps leaving the background stationary.
• finder highlights first app matching the search string, so no need for quicksilver any more
• i like the organisational panes in the finder, but i'd still like a tabbed finder (as pathfinder is hopeless at creating folders in the right place).
  
• quick look seems pretty handy, but why doesn't it work from dock stacks?
  
• aperture is working ok in general, except one problem with the filmstrip HUD which sometimes re-appears when not in full-screen mode, perhaps relating to spaces?
• oh, and ctrl+s doesn't work in aperture any more (should add a sharpening control to the adjustments pipeline), maybe something else is hogging the key combo?
