I already have checked armory but it seems its not fully portable and is only an addon for the normal client. So that the normal client has to be used anyway.

Online wallets are too insecure for me. I mean why taking the risk to give another person all your bitcoins only for letting them lay there? That sounds too risky, especially in the bitcoinworld.

Downloading manually might be possible but it takes work and probably some time for downloading too. On top you need to trust the source. But maybe there is a client that does this automatically and in a secure way? So that its faster and secure?

Multibits points sound all nice. I think i will give the beta a try so that i can encrypt the wallet. And ill wait for the feature with the single addresses. Because then its a bit more anonymous because addresses cant be connected together so easily.

Thanks!
