I completely agree. There are many areas that need a much higher priority like the ones you mention and many more. A replacement for Google Earth seems out of place for even being on the list.I don't even really agree with the Free Software Foundation's listing of this as a high priority project for the success of free software; a free software version of Google Earth isn't going to make or break it for free software and the Linux desktop. I (and likely many more users) would much rather see language learning software (i.e. Rosetta Stone replacement) or proper tax/accounting programs (i.e. TurboTax replacement) on this list instead, which would affect a lot more people.
