From my post today (as 'bugger') on an Apple Support thread: 'Me too; Serial W8543... etc., etc. As I recall it started about 6 months ago with something -' (like a neg. scratch in film) '- that was intermittent; faint and gone when up to temp, but by the time I was looking; a - here -' (Support) '- for answers and b - for the corrected paperwork (original one's power supply was declared DOA after one week home and three in the shop -' (January '06 so of course I'm out of warranty) '- I had a thin green line top to bottom through the flag (usually) then for couple of weeks now it has been joined by a bright red through the airport symbol and in the last few days I've noticed two more greens; one beside the time and one through bluetooth, but also sometimes ie. while screen is waking, colours vary and 'echoes' are visible as well these present fixture 'artifacts' We are north of Cairns so coping with power outages, humidity, and other factors makes us prone to low expectations of low-end products. This purchase was to replace a G3 (power supply -' '(/ies) '- which replaced the LC (rusted motherboard) we brought up here with us in November '95, so - while I appreciate the upgrades - I would like to see Apple's examination of this phenomenon and look forward to a response with our allegiance in mind.' I chose not to mention the intermittent 'coma-with-fans' problem. What would be the business formula for: edgy-design / quality-control / extended-care-claims / customers - swings and roundabouts?
