HAPLO  Ok, firstly as much as I like the new interface, it's way too big and bulky. The page dock is cool, but both the dock and the tab bar are now about double or quadruple in size from the original. One thing that makes or breaks a browser is how much screen space it gives you for actually viewing the page. Now if you're running a freaking 30" screen the new interface would be great since you have more screen space than a page would use anyway, but for my little 14" iBook this is fairly horrid. Also, there's a good two inch thick bar below the main toolbar that seems to do absolutely nothing. Yes, you can collapse the dock, but the status bar below is also pretty intrusive, and you really don't get much space with this.

Secondly, full screen looks nice but is highly nonfunctional. The draggable Quicktime-esque control bar is kinda nice but there needs to be a better way to show/hide it, to make it smaller (ie small icons) and to include an address bar so it can actually work.

Overall, even for a beta, just assessing the new layout, it's really too much superfluousness and not enough function.

HAPLO  The address you provide seems to resolve to this:

http://www.macupdate.com/~matt/devel/info.php/id/14516

Check that link, it's messed up somehow. I haven't had any other problems on macupdate, so this seems odd.  
(Version 1.2.1)

HAPLO  Ok, the download link is pointing to an html file that links v1.1.6, which is corrupted. I can't download 1.2.1 at all, and I've tried both camino and safari.  
(Version 1.2.1)

HAPLO  The link target is wrong, it points to an html, but following that downloads, but the file is corrupted. Neither the system decompressor nor stuffit will open it.

HAPLO  Extremely useful and 348976x better than packagemaker. Packagemaker is just too much work and too much lower level digging to do simple things that are only a few clicks with iceberg.

However, the download host used for this is TERRIBLE. I have yet to be able to successfully download 1.2. Mirror it somewhere else >_<.  
(Version 1.2)

HAPLO  Wow, this is pretty godly, especially if you're on a laptop. It lets me fully view documents that don't scale well in preview or maximize my screen space in camino. It also switches modes nicely and retains the functionality of the menu bar. It does disable the dock though, but typically if you're using it you'd command+tab or else you'd need to un-fullscreen in order to open a new app anyway.

However, this in addition to quicksilver really makes life easy.

HAPLO  ROFL. Just... ROFL.  
(Version 1.1)

HAPLO  I don't suggest VPC. Back when VPC was run by whoever used to own it, it was good. Now it's just microsoft windows with Microsoft Virtual Computer™. Bochs is not very good regardless, I've heard that QEMU is better, plus QEMU will install more than microsoft products and can emulate more than just x86. Also, some dude with more free time than me made Q. I'm still trying to get a copy of XP Pro, but Q lets you do everything worthwhile that VPC can do (including save states) only it has better drivers and is faster, and has much better CD/DVD support (you can install to Q from a windows/DOS CD or DVD). Also, VPC has no support for other save states, but Q can import guest machines from VPC7. Did I mention Q is free?

HAPLO  Heh, if you're a percussionist like me, this widget is great. 4 beats and it's got it. I can only wonder how those with less accurate timekeeping abilities would do with it though.  
(Version 1.3)

HAPLO  Well, maybe not logitech, but I didn't have any trouble setting up a microsoft intellimouse before I had my mighty mouse o.0. I find it amusing that I can use a m$ mouse, yet I'm fairly sure you couldn't just pop a mighty mouse into a PC ;P.  
(Version 1.6.2)

HAPLO  Can't you do all of this stuff with apple's control panels anyway? In Tiger you can set F-keys to do custom actions and configure every button of their mighty mouse to do anything you want it to, including exposé and dock actions. The major difference? Apple's control panel won't suddenly cause your keyboard/mouse to stop working, and all of the custom functions actually work.  
(Version 1.6.2)

HAPLO  Although the occasional beta will crash and not come back till you update or revert, this is probably the single most useful application ever developed for OSX. As an application launcher, it's the fastest and most effective I've ever used on any platform. I used to use it to control iTunes (although that's only good if you actually know the artist/name of the song you want to listen to next) and it was great for that too. It's especially good for programs you use occasionally or even a lot, but don't want to put on the dock. It's really even faster than the dock, so I use it for things I put on the dock, too, on the occasion.  
(Version 1.0b48)

HAPLO  Skype, at one point, was good. Now it's a peice of crap. They removed echo cancellation and all of the advanced audio features, the program is no longer able to reclaim username/password information from older versions, and the sound cuts out constantly on a cable-cable connection. It's worthless now. In fact, when comparing the audio to iChat audio, it is only about half as stable, so bad that you can't actually get anything from what the other person is saying. Didn't used to be this bad, but it is now.  
(Version 1.4.0.35)

HAPLO  This is awesome. iTunesLyrics never found lyrics for ANY of my songs. This thing has succeeded in everything I throw at it. Hell, it even found "Rising Force" by Yngwei Malmsteen, lyrics for various songs by Sonata Arctica, a song by Rhapsody that I couldn't even find manually... Very Nice.  
(Version 0.2)

HAPLO X  The more I use this, the more useful I find it. This is by far the most useful program I've found in a LONG time. You can launch apps with it in a second, you can control iTunes with it, you can even do math and get dictionary definitions. One thing though, I have yet to get the weather plugin to work >:[.
