Tflo3d can be annoying for someone who is used to eveything on one screen like must of us winmo users. I had a version of HTC home on my
Mogul and liked it very much with today agenda below it.
I will say that I now like TF3D. I will add that I use tf3dconfig to remove some tabs (music, internet, and people) as I use different options for these (nitrogen, opera mobile beta, and voice command).
By cutting the tabs down to 7 and moving programs to the extreme right (instead of one from the right like stock - stupid) - I have come to a compromise that I like. I use these tabs in this order - home, sms, email, album (pics), weather, settings, then programs - it is very nice. I also will add that the music and internet tabs are the most memory-hogging as they cache alot of info, so nuking them also opens up a lot of ram.
I fought using tf3d for a while, but when I made myself use it for a week or 2 and tweak it (like everything else in winmo) it suits my purposes very well.
PS - LOAD A CUSTOM ROM!! - this is not quite as necessary on Sprint as it is on Verizon, but still - I think worth it.
