Hi JP,
Sorry, but I'm not from/in Bonny Scotland (I'm a Londoner), but I will contribute that I am a UK SL-C860 user, and I love it! Before I bought an SL-C860 I had the typical SL-5500 and loved that too... but the 860 is so much better. Faster, lots of application memory, absolutely beautiful screen, nicer build quality, the keyboard is a lot nicer, the battery lasts a lot longer, the on-board speaker is cool, the jog dial and side-mounted enter/cancel buttons make it into a veritable mp3 player.
After moving on to the 860, the 5500 has been relegated. I advise the Cacko ROM 1.21 for the C860. This ROM works well for me.
Enjoy,
Edo.
