The T-Mobile G2 is the true successor to the G1. What is unique about the G2 is that it will be the only Android handset with a physical keyboard that will run on the stock, or ‘clean’, version of Froyo. The handset is therefore labeled as a ‘With Google’ handset, which could potentially mean that any updates to Android itself may appear quickly on the device. Like Samsung's ‘Epic’, the G2 will also be able to handle ‘4G’ speeds, even though the HSPA+ network from T-Mobile differs from Sprint's WiMAX. The handset runs on a SnapDragon processor, running at 800 Mhz. As it is a newer generation of the processor as compared to those running at 1GHz, the phone should, in theory, run even smoother at the lower clock speed. Furthermore the phone has 4GB internal memory with an 8GB SD card included, shoots 720p video, has a 3.7 inch Super-TFT screen and 512mb of RAM, making it a top of the range handset.
The MyTouch 3G Slide is T-Mobile's mid-budget slider Android phone. It is a successor to the original MyTouch 3G that did not have a physical keyboard. The Slide characterizes itself by running on a heavily modified version of the Android Platform, that somewhat resembles HTC Sense in some ways. As the phone is produced by HTC, this doesn’t come as a big surprise. The fact that it is a mid-range phone is evident through the hardware specs. Compared to the G2 it has a slower processor, running at 600 MHz, with 512 MB a lot less internal space and a 3.4 inch screen. Nevertheless as the phone is part of the MyTouch line of T-Mobile it is well supported and therefore a worthy alternative for everybody that doesn’t need a more expensive high-end handset like the G2.
The Motorola Cliq is not necessarily the worst handset with a physical keyboard available on the T-Mobile network, but it doesn’t have many of the features that the other two have. As it is also the oldest of the three, and the first phone to feature Motorola's ‘Blur’ interface, the handset has the lowest hardware specs, albeit only slightly less than the MyTouch 3G Slide. However, as Motorola has not dedicated itself to updating the software version of the phone beyond version 1.5 of Android, the phone has a lot to catch up on at the moment. If the T-Mobile G2 is ‘High End’, and the MyTouch 3G Slide is ‘Mid-Range’, then the Motorola Cliq would be the ‘Low End’ offering.
