This is currently what I'm rocking with on my lock and home screens I think you'll find the weather particularly interesting.. it doesn't go into details like the windows mobile versions you mentioned (no sunrise/down info, radar pics, humidity, etc). But a nice looking 5 day forecast eh? and on the homescreen no less.
Apps I use for serious stuff are as follows:
*LockInfo (for jailbroken devices only... found on cydia)
*AP Mobile (news)
*Bible Reader or Logos (requires genuine conversion to be thoroughly enjoyed)
*Pocket Informant (AWESOME to/do calendar app that syncs with google and toodledo websites $12.99... worth the money)
*Evernote (Random thought/note collector.. syncs wirelessly with evernote.com and desktop versions FREE)
*Pocket Money & BillMinder (I mention them both at once because they work hand in hand for me.. and it's great that billminder and export bills and payment info directly into pocket money. This has replaced desktop quicken for me and is used closely with the mint.com app. Pocket money supports backups via email and wirelessly to the desktop and exports qif files).
* dictionary.com app (nuff said)
* dropbox.com app (kinda pointless other than playing vid/audio files and deleting stuff.. but i still find that i use it quite a bit).
* spb Wallet (store private info securely and have it available to you at all times.. priceless)
* The Weather Channel App (just because)
