How is the situation with packages/ports nowadays and web browsers on OpenBSD ?
Seems pretty decent, probably better than it was a year or two ago when there were no javascript-capable browsers. otter-browser is stable and handles javascript sites without much trouble. It's reasonably light for a full featured browser. I mainly use Netsurf and lynx because they are blazing fast. Dillo works and is very fast too, but its renderings are a bit rough.
There are enough packages available that besides the web browser I really don't have to change my workflow from my Intel laptops because I'm using the same tools, so claws-mail for email, xpdf for viewing PDFs, wordgrinder for writing documents, mplayer for audio. All the network admin and pentesting stuff is the same (nmap, arp-scan, arping, etc).
