LG Optimus 2X review: Comparison
Well, it's hard to put the LG Optimus 2X in the same bracket as anything currently on the market when it comes to the internals. The Samsung Galaxy S2 and Motorola Atrix will catch up with it, as will the HTC Sensation but it's unique so far.
However, from a design and software point of view, the Optimus 2X isn't a million miles from lots of phones on the market.
LG's own Optimus One actually isn't the closest around, because the front aesthetic, four-inch screen and touch-sensitive buttons of the Optimus 2X bring to mind the HTC Incredible S more than anything.
Android fans looking for sharp performance would do well to check out the Google Nexus S or HTC Desire S and the improvements Android 2.3 brings. The Nexus S's, the Samsung Galaxy S, would also be worth checking out, if you can't wait for the next version to arrive.
If it's sheer slickness and speed in the operating system you're after, the iPhone 4 has to be a contender, as do Windows Phone 7 devices, such as the HTC HD7 and the Samsung Omnia 7, which sports a stunning AMOLED screen. LG also has a WP7 device in the shape of the Optimus 7 if it's the brand you're after.
