I see the scheduler function in color note as a complement to my calendar not a replacement. I use it to remind me to do specific tasks that don't run over a set time period. So if I have to remember to update something or send an email on a particular day I can set the reminder and my phone will remind me.

My daughter found that you can set up a note in Evernote as a "to do" list.

I've just ordered myself an Android tablet. I went for a 8" tablet (4:3 format) as I felt the 7" tablets weren't quite big enough. While looking round the net I noticed quite a few complimentary comments about the Android version of the Opera browser. I've just downloaded Opera for my Linux netbook as Flash had been disabled in Chrome (It said it was out of date) and it is certainly much quicker than Firefox, so is worth a look.

Someone mentioned Juice defender above. I'd forgotten about that, very useful and also setting sync to manual. Both useful battery saving methods. Reducing display brightness is also a good idea. You can display a breakdown of battery usage, at least you can on my phone, and display comes out as the largest user of power.
