Google Nexus One vs iPhone 3G: which is better choice for video playing?

Now that Google’s Nexus One phone has been revealed, the question everyone is asking is how does it compare to the other current top smartphones on the market? Moreover, is it worth switching to Nexus One from your current device? Now, I have narrowed down my choices to Google Nexus One and iPhone 3G S and I’ve had a really tough time choosing between the two:
Display
Thinner than iPhone, Google Nexus One features a 3.7-inch (9.4 centimeter) AMOLED (Active-matrix organic light-emitting diode) touchscreen display. Measuring 119mm (H) X 59.8mm (W) X 11.5mm (D), the phone offers 800x480 pixel screen resolution.
On the other hand, iPhone 3G S comes with 3.5-inch LCD capacitive touchscreen display with 320 x 480 pixels. The phone measures 115.5 x 62 x 12.3 mm.
Operating system
iPhone's current model runs on iPhone 3.1 OS. The phone is powered by ARM Cortex A8 processor. Among key features, the upgraded software now lets users cut, copy & paste, a sorely missed feature in the iPhone 2.0. iPhone 3.0 also offers multimedia messaging capability with the new 3.0 software allowing users to send each other photographs from the phone.
Nexus One will run on Android Mobile Technology Platform 2.1 software, the most recent version of the mobile platform offered by Google. The phone has a 1-GHz Qualcomm Snapdragon processor. Android 2.1 which add several 3D user interfaces features and lets users customize home screen.
Battery life
Apple claims that iPhone 3G S supports up to 12 hours of talk time, 30 hours of audio, 9 hours of Wi-Fi, 10 hours on video playback, and 5 hours of 3G talk time.
According to Google, Nexus One will offer talk time of up to 10 hours on 2G, up to 7 hours on 3G. Standby time is up to 290 hours on 2G and up to 250 hours on 3G. The phone offers video playback of up to 7 hours and audio playback of up to 20 hours.
App Advantage
Apple iPhone App Store iTunes offers people over 90,000 apps. Nexus One, on the other hand has its own Android Market that offers mere 20,000 applications.
Multimedia
Unlike iPhone, Google's first-gen handset offers a 5 megapixel camera (with auto focus, a 2x digital zoom and LED flash) and video recording at 20fps (720 x480). It has build-in multimedia player and supports: MPEG-4, H.263 and H.264 etc video formats and MP3, AAC, AAC+, eAAC+, WMA, AMR, WB/NB, WAV&MIDI, etc audio formats.
The third-gen iPhone packs a 3 megapixel camera with video capturing, auto-focus mechanism and editing capabilities. The earlier two versions shipped with only a 2 megapixel camera each. And it also has multimedia player, but supports: MPEG-4, H.263, H.264, M4V&MP4, etc video formats and MP3, AAC, AIFF, WAV, VBR &Apple lossless, etc audio formats.
Both are good multimedia smartphone and support many video and audio formats. But, if you has a AVI file, how to play it with both two smartphone? I get answer from Google search. You may try Nidesoft Video Converter which could convert video or audio files between all popular formats to convert AVI file to MPEG-4 format. Detailed process is as follows:
Firstly, you could free download and install Nidesoft Video Converter from: http://www.nidesoft.com/downloads/video-converter.exe.
When you finished the download process, run the .exe file to install it.
Step 1: Click “Add File” button to import your videos from your computer.
Tips: Click a file in the list and you could use the preview control buttons to play the file.
Step 2: Click "Format" combo box to select the output format, such as to mp4 for iPhone.
Step 3: Click “Convert” button to start conversion. The conversion will be completed in a short time.
Ok, now you have converted your AVI files to MPEG-4 format files which iPhone 3GS and Nexus One supports and you may use it more convenient. Another I also find Nidesoft DVD Ripper could rip DVD to multimedia phones’ video and music: 3GP, AVI, WMV, MP4, WMA etc. So, it is not a problem to watch your favorite DVD on mobile phone. I think these two Nidesoft software are necessary additional software for mobile phone users.
As for memory
Nexus One packs 512MB Flash, 512MB RAM and 4GB Micro SD Card which can be expanded to 32GB.
Apple's third generation iPhone comes in two memory options, 16GB and 32GB. The phone has 256MB RAM. But iPhone 3GS doesn't have a card slot for further memory expansion, which is a sore point.

At last, a big disappointment in Google Nexus One is that it doesn't support multi-touch functionality unlike Apple iPhone 3G S. And a trademark of Apple, multi-touch allows users to interact with the device by placing two or more fingers directly onto the surface of the screen.
Android system smartphone has been favored by manufacturer, after all, only it may compare with Apple. But the Android system is not totally same the apple and we also see a new innovation from Nexus One. But as the first independent brand phone using Google, the Nexus One may be the best Android system phone as so far. If it can be become the biggest competitor for iPhone, we still see!
