Totally agree. "Stand on Zanzibar" has a modern-world feel to it although some parts have been visited by the Suck Fairy. "Shockwave Rider" is also interesting - IIRC characters use their landline phones to access large computer systems. Because Brunner never really goes into too many techy details - it's just phones and computers - it's less jarring to read now than books where technology-heavy authors such as Arthur C Clarke tried to describe in detail what future computing devices might look like.
