I used Weather Forecast Widget v2 for a while. It shows your upcoming agenda with the weather forecast next to each day.
I like Calendar Pad Pro. In the month and week view, it shows the name of the appointment, and the color (based on the Google Calendar I put it in. I divide them up, Self, Work, Family, Holidays). Makes it easier to see what's up at a glance.
I'm hoping at some point the developer of DateBk6 (on Palm) will get his new application ported over to Android. I like the use of icons. With that in the month view, I don't even need the name of the appointment, usually the icon is all I need. (e.g. icon of a doctor, icon of a phone, icon of someone teaching, etc.)
I just use the Calendar on Beautiful Widgets. Not only is it a widget but shows the date. I tap it, and it takes me to my calendar and I can pick what i want. Less apps downloaded, less memory taken, and I have free space on my homescreen or extra screens. Also the widget has a clock and the weather. Best. Period
