I use the Weather and calendar gadgets, after trying out others these are the most useful (to me). Anyone who lives in East Lincolnshire, UK, will tell you that we often have different weather to nearby areas. Something to do with the Lincolnshire Wolds and our geographical position, I believe. The Lincolnshire Coast bulges out into the North Sea, to the east of the Wolds. The local weatherman often gets it wrong, but I would say that the Weather gadget is more accurate.
The Calendar is useful to a Senior who often forgets what day it is (sometimes the year, although I am usually OK with the Millennium!) All gadgets can be set to degrees of opacity and I find that this is very handy as it hides them until I need them.
As long as I can keep the gadgets I have, it will mean very little to me that the rest are dropped. Lots of other similar stuff available, as has been said.
