Old technology but good
The Olympia Traveller C is, unless I can find any others, the last manual typewriter being manufactured anywhere in the world. Yes, it's totally obsolete technology but then, it doesn't need batteries, the kernel will never panic, there's no screen to have the BSOD, and no self-respecting thief would ever look twice.
My second-hand typewriter (made by the unknown company ABC) is nice, and very useful for writer's block. The limitations and the concentration needed to type properly, hitting each key firmly and independently, is a wonderful experience after cheap PC keyboards. It seems to break writer's block every time. The change focuses the mind, and I've never typed 'teh' or 'mutlicluturalism' yet. The price I paid for it was excellent, after retrieving it from a skip bin full of building rubble, but it's limited. It's pre-decimal currency, for a start.
I want one. Now I just have to find somewhere that stocks it, and a decent justification to spend USD $78. So far I have none of those three things, especially considering the counter-appeal of giving my money instead to this.
UPDATE: According to Will Davis' really frightening typewriter site, the Olympia Traveller C is no longer in production. Rest in peace, manual portable typewriter.
UPDATE2: Chee May (Goh's) Pty Ltd of Hong Kong still sells manual typewriters. Hurrah!
