EMEL TRAW  I was a happy iBank 2 user for a while but over time it just got slower and slower and the pie charts started acting very flaky. iBank 3 had come out so I looked around online to see what people thought and was very disappointed to see people saying that it was just as slow as iBank 2. I switched to Moneydance and am very happy with it except that I miss iBank's clean look.

iBank had a lot of promise. I hope the developers will focus more in the future on making the basic functionality really great instead of gimmicky features like coverflow that seem more about winning Apple design awards than making it better for users.

EMEL TRAW  I'm another happy switcher from iBank. iBank started great but got slower and slower over time and before long was completely unusable for editing a file on a shared drive over my wireless network. Moneydance imported all the accounts from iBank with little trouble, and is super fast with the same data.

The only downside is that the UI is not very Mac-like but the speed and reliability make up for it. Data entry is much easier than in iBank too with much less switching between mouse and keyboard needed and nice shortcuts like "t" to set the date to today.

Even if you would not usually use an app that isn't 100% "Mac" Moneydance is very worth trying out.

EMEL TRAW  @LEOOFBORG: its possible for someone to have a different opinion from you without being paid for it so get over yourself. I like Google Earth and saw that there was wrong information here that might scare away other people who might like it.

If you don't like the program good for you. I don't call you a Yahoo or Microsoft puppet.

EMEL TRAW  Wow, there sure is a lot of fearmongering here. I installed Google Earth 5 to see what all the fuss was about and poked around afterward, and here are some actual facts for those interested more in reality than conspiracy theory.

* The updater process does NOT run as root. It is a launch agent (not a launch daemon) which means it runs as your user not as root. It couldn't run as root if it wanted to, because it never asked for my password. @MISTERE: a plugin with an installer isn't the same thing as Google Earth. Maybe that runs as root but this doesn't. @LEOOFBORG: maybe you should learn what a rootkit is before you make crazy accusations. This updater can't do any more naughty things than any other software you open and don't give your administrator password to.

* It doesn't run all the time. Its launchd plist says it only runs every couple of hours. From what I saw it quits almost immediately, probably just long enough to see that there are no updates. Anyone running an application with Sparkle in it is probably using more resources on Sparkle then they are on Google's updater.

@NORBERT: if you think spyware is going to ask before installing, you must not have used Windows much. The whole point of spyware is that it installs without you knowing so it doesn't matter if people are used to allowing some software to run in the background when it asks. And how did Google Earth install without your knowledge and permission? Did you not get the dialog explaining it was going to install an updater and require you to give your permission? It did for me.

@everyone who thinks running things in the background is unacceptable: open Activity Monitor and see how many of the things there you gave permission to run, or even know what they do. All kinds of things run in the background on your computer all the time.

Oh, I hope everyone below is boycotting Apple too. iTunes nefariously runs something called "iTunes Helper" in the background even when you aren't running iTunes. They never even asked or explained what it does.

For the people who don't want to pass up one of the coolest free apps out there to hold on to an illusion that you control everything happening every second on your computer, some comments on the application, since noone else is actually talking about it here:

* The UI is still a bit weird, but at least its less ugly than it used to be

* Historical view is very cool. It can be hard to compare in big cities because building shadows are so different in different images but other than that you can see lots of cool changes an a huge scale

* The new Mars view with all the extra NASA pictures and stories is a lot of fun if you want to see all the Mars exploration in context.
