Where do you install your applications?

i instal everything on my mem card except my theme and my ring tone which go on fone mem and handy taskman, everything else goes on mem card, i like to keep my phone mem as clear and clean as i can, just dnt like a messed up phone drive by having junk left behind after trying and uninstaling an app

I install the most important bits of software to phone memory e.g. Route66, Worldmate, Flurry, Gmail app etc.. because I've had memory card errors in the past and also if I forget my memory card in the card reader (at home) I wouldn't be lost. I tend to use my memory card mainly for pictures, videos, music etc..

I use the phone memory for apps that need access to internet or have running all the time, as I get fed up with having to close them down when sticking a USB cable in to access files on the card.

Sorry for reviving an old thread but I was wondering if there is much speed/access time disadvantage to installing on the mem card. I thought there was and I install almost everything on the phone but that makes firmware upgrades a long and drawn out affair!
