Currently using a Google Nexus One on Telecom XT – unfortunately this doesn’t belong to me. I have a Galaxy S, but some fool on trademe sold me a Vodafone version as a telecom version! . I love the fact that I can do whatever I want with the N1, install any software etc. It’s running CM 7.
Android does lack some of the polish of iOS, but it’s definately the geek choice for smartphones (well I think so anyway). Running OpenVPN on my phone makes my work (As a SysAdmin) so much easier.
Because I’m heading overseas in the not too distant future, I’m thinking I’ll want a quadband phone, which pretty much leaves me with one choice, iPhone.
