As we pointed out earlier, the X10 Mini and Mini Pro share identical guts: Qualcomm MSM7227 600MHz processor (as featured on the Legend, Aria, HD Mini and MyTouch 3G Slide), 2.55-inch 240 x 320 LCD capacitive touchscreen, 5 megapixel autofocus camera, microSD expansion, micro-USB port, FM radio, A-GPS, Bluetooth (with A2DP), and 802.11b/g WiFi. Phew! Now what really differentiates the two models is the Mini Pro's slide-out QWERTY keyboard -- we dig its tactile feedback and spacing between the keys, although it did take some getting used to with the oddly-positioned shift key, and not to mention the non-offset rows of keys. To pack all this goodness, the Mini Pro therefore has a slightly longer and thicker body (we measured 18mm vs 16mm), but both devices feel just as good and secure in our hands thanks to SE's signature "human curvature" design.
Those who are super picky with their phone's color may be somewhat limited by their choice of carrier -- there are six options in total for the Mini: metallic red (our favorite), lime, pearl white, black, glossy silver and glossy pink (not so hot on the last two); Orange UK only stocks black and lime, for example. On the other hand, the Mini Pro only comes in black, pearl white or red (the latter two not pictured), and no, you can't fit the Mini's shells onto the Mini Pro due to the different sizes and button layouts. Even if the cases were swappable, we wouldn't be keen on doing so on a regular basis -- from time to time prying them open was as difficult as picking warts off our feet.
