oh geese! from that post to this post, i've installed and uninstalled that, its VERY impressive, but i dont suggest it unless you have tons of space on your computer! just between now and then i went up to 2 gigs of information
its got tons of neat things, but the quality on the pictures around the world isnt as nice as google is, however it has tons of interesting things to look at and different map types etc. but if your computer doesnt have much space (even though i have 20 empty gigs, i am still skeptical that im near 20 free lol) but hey.. if you got tons of space to spare go ahead, its pretty interesting!
one last thing; sadly it also takes FOREVER to download things such as tracking hurricanes and such.. wanted to track hurricane francis, but.. got about 1/8 done in about 30 minutes so.. owell its quite nice though
