Phone You Are Using

I know Dreamcat has set this up for the tablet community, but thought it might be interesting to see what kinds of phones people may be using and are they integrated into their tablet for various programs.
All my devices are integrated. Running Windows 8 on both the EXOPC and the Asus. Have HTC 8X on ATT, and Nokia Lumia 822 on VZ with WP8. The Xbox 360 is of course also in the mix.
Lastly, what is the perfect screen size for a phone?

I am using an iPhone 3GS on T-Mobile (my LG G2X broke, so I went back to my previous phone after having it unlocked).
The integration with my tablet (and desktop) revolves around my Google account. I have my calendar, contacts, and email synced between my Win8 log on and my iPhone.
So, no matter what device I am using at the time, all my reminders pop up on the screen and all contacts are recognized.
Using the CardDAV and CalDAV sync options on an iPhone, plus installing the mobile Google Chrome, gives me the parts of an Android phone that I like (having it based around my Google account and the Chrome browser), while still having access to the iOS app store.
With Win8's ability to sync my log on with my Google account, it all seems as if it is one system. Even though I am on Apple and Windows devices, using a Google account.

I have a Galaxy Nexus -- a true Google device. I have read on Engadget that Verizon will be pushing Android 4.2.2 to it any day now.

I use FoxFi through the Bluetooth connection on my phone to get Internet service on my EXOPC Slate without paying teathering charges to my carrier. There have been many times that having a larger screen, access to my programs, and the peripherals on my tablet let me do things that would have been difficult on just my phone. Two weeks ago, I used my EXOPC, my data projector, a USB Web cam, and Internet through my phone via FoxFi to hold a Skype video chat to allow a Board member to be part of our meeting and see all the participants; we got to see him at more than lifesize on the wall.

I also have Unified Remote on my phone. It allows me to connect the phone and tablet via Bluetooth and control the tablet and send various programs control codes. I can move the mouse and type on my phone in any program. I use it to control Windows Media Center.
