Synchronizing stuff between your computer(s) and mobile device(s):
- Files
Dropbox is a cloud application that allows you to share files between all your computers and mobile devices. It supports PCs, Mac, Linux, iPhone, iPad, Android and Blackberry. And even if you're away from your own computer, you can acess your files from the Dropbox website. 2GB is free, more storage is extra (BTW, if you contact me about Dropbox, we can both get additional free space through a Dropbox referral promotion)

- Bookmarks
The Xmarks tool (formerly called Foxmarks) installs as a plugin for Firefox, Explorer, Chrome and Safari and lets you keep the same bookmarks on all your computers. The PC-only version is free, The Premium service includes syncing with iPhones and Android broswers (even a plugin for Android's excellent Dolphin browser) and costs $12/year. Can be combined with the related LastPass system for synchronizing passwords.

Also, if you use Firefox as your main browser, you can use the free Firefox Sync which is built into Release 5 for PCs as well as Firefox for Android
- Notes
Some people like Evernote, but I prefer Catch as a fast way to make notes that are then available on all your PCs and mobiles. I especially like the Android widget, and you can use your existing Google or Facebook account to sign in. Free for basic use, you can pay for more storage.

- Photos
I'm still getting used to the integration between Picasa and Google+, but find that the combination works very well in managing photos and videos, whether uploaded from your camera or taken by your phone, It works especially well with Android phones. Let me know if you need a Google+ inviation. Completely free to use.

Hope you find this of help.
