One more thing worth mentioning for anybody thinking of doing likewise, and maybe of special interest to Weaver...
...No internet, none at all.
Many places, including where we stayed, had no Vodafone mobile signal at all. Where we did get a signal, it was only GPRS or Edge. The only place I found 3G was in the immediate vicinity of the Calmac ferry terminal at Tarbert, I guess they have a femtocell or something?
Outside town, guest houses generally did not provide WiFi either, I'm guessing their line speeds were too pathetic to share with their guests.
But if a digital detox appeals to you, it's the place to go. After my withdrawal symptoms abated, I found it added to the relaxed atmosphere.
