A great many Ruby books seem to work on the assumption that you absolutely must be developing either on a Mac or on Linux. It is refreshing, therefore, to find a book aimed at Windows users.
Antonio Cangiano’s book, Ruby on Rails for Microsoft Developers, is just such a book. I haven’t had a chance to grab a copy yet but I’ve had a browse on Amazon and it looks just the ticket for Ruby On Rails developers on the MS platform. I must confess that I am also pleased to note that it contains a few nice mentions of Ruby In Steel... ;-)
