A Call to Action: Decent Twitter client for Linux and Windows Mobile

I have been trying to resolve a special problem. My special problem is caused by my being a gadget freak who has both a Windows Mobile phone and an EeePC. Although I can survive through mobile Twitter and full size web Twitter, I am not really growing. I need a proper app for Twittering as I have on my Windows PC, for both my more mobile devices. I have looked and looked and not found anything of note for either platform. Please someone who has the skills…. anyone got a client on the go for these platforms?
