I thought it had died already. I've never cared for it, it seems very clunky and un-apple like. I have tried to make use of it in the past but never found any of the widgets very useful.
Which widgets do you use?
I can quickly access Dashboard with a click on the scroll wheel of a Logitech mouse; the Apple mouse has no equivalent trick as far as I know. I frequently use:
Clock, several set to different time zones.
Sun Clock, which tracks night and day throughout the world, adjusting as the diurnal cycle changes throughout the year.
Calendar, to quickly check on dates for future planning.
Unit Converter, most frequently to check exchange rates, but also other conversions….. Especially between metric measurements used by most of the world, and the units used by the USA, which are often different from the Imperial units I grew up with, and were used by many countries in pre metric days.
Phantom Gorilla, to stream BBC radio stations.
iTunes timer, to put the computer to sleep half an hour or so after I go to bed, often listening to one of above mentioned BBC radio stations.
iStats to monitor the status of my HDD. Still on the original 120 GB, it can fill up quickly with photos over the course of a local cricket league season, before I delete many, and archive the rest on an external HDD.
And others from time to time.
I would use
Tides if it had local information available. In Thailand it only has Satahip, in the Gulf of Siam, far from the Andaman Coast, where I am at. Back home in NZ it will be more useful, with coverage of many places.
Haven't checked recently, but App Store has many widgets available (some free, others for a fee) which would be applicable to different situations.
