Got myself a Palm VIIx from www.ebuyer.com this week, for the give away price of £28 delivered, has 8Mb and backlight. Personally I'm not one for diaries/organisers, but there is lots of free/cheap software available for it a couple which are very useful.
And I can use it as a glorified remote control, I've also tried the excellent 'What's On for Palm which is free this is a tv guide for the palm that takes advantage of XMLTV, it's fast and 7days worth of listings take up a tenth of my 8mb memory checkout http://www.zookware.com
So I'm all set with a tv guide and remote in one handset, noticed http://www.radiotimes.com/content/features/services/ try to sell there palm guide for £15 per year.
Note: don't expect the batteries supplied to last long, the VIIx has a built in wireless aerial that has an internal battery which is charged up by the 2 AAA's, as yet I've not figured out how to turn off the wireless capability as the service is no longer available. But my rechargable AAA's are holding up well and should last to quoted few weeks on a average usage.
