The Sony-Ericsson Xperia X10 is one of the earliest microprocessor-driven smartphones to use 32 GB of memory on the market, using the 1 GHz Tegra processor and it is one of the first to use the Android operating system, while the Samsung Galaxy I9100 S II, one of the latest on the market that still offers 32 GB of memory, but it also offers the latest in display technology with a superAMOLED Plus touch-screen, and a dual-core Tegra processor.
When the Sony-Ericsson Xperia X10 was introduced a couple of years ago, it was really a world-beating smartphone at it offered access of up to 32 GB of memory, a 1 GHz Tegra microprocessor and it ran the freely accessible Android-based operating system so that users had access to thousands of apps.
When you look at the Xperia X10 versus the Samsung Galaxy S II, you may notice that Samsung offers the latest and greatest version of Android 3.1 with access to more than 200,000 apps, while the X10 can be upgraded to about 2.3.1 which means that though there are still thousands of apps available, you do not have the same range that is available today, nor do you have the same WiFi range. Where the Samsung offers 802.11 a/b/g/n, the X10 offers 802.11 b/g/n. This means that while both can find public hotspots, the Samsung is able to take advantage of higher speed WiFi networks.
One of the features that is neat about the Xperia is that it does offer a slightly larger on-screen QWERTY-style keyboard so texting and email access is somewhat easier on your thumbs or forefingers. In fact, if you are good, you can probably get two-fingered access to the X10, though the touch-screen is nowhere near as bright as the Samsung whose superAMOLED Plus technology gives you not only high-definition quality displays, running at a native high-resolution speeds of 1080p (the X10 does about 720p which was good a couple of years ago) with the right app on the Samsung you can interface your smartphone to a high-definition device and use it for streaming video or audio. Plus, the superAMOLED Plus screen's colors is brighter, crisper and its contrast is brighter so that you have excellent rendition on a small device.
Both the Xperia and and Samsung are about the same size, but the key difference you will find is that the Samsung software has been optimized to take advantage of each processor and its power so that it can do true multitasking such as taking texts while you are streaming audio, while the Xperia can handle one item at a time. Or, it can handle more than one, but you will find you have to break out of one to move to the next.
The keys to both of these devices is the fact that they are Android-based and as such have a wide variety of apps from which you can take advantage.
