With the Sony Ericsson Xperia Pro delayed till July and possibly beyond, prospective customers might be enticed to look at its predecessor, the Sony Ericsson Xperia X10 Mini Pro which also comes with a keyboard but is significantly smaller.
T-Mobile still sells the Xperia X10 Mini Pro (via Buymobilephones (opens in new tab)) for £11.15 on a two year contract with 100 minutes, 100 texts and unlimited data which brings the total cost of ownership over the two years to around £268.
Those looking for that handset without being tied to a contract can go to Carphone Warehouse (opens in new tab) where it is available on Pay as you go for £144.95 including all you can eat data plus 3000 texts and 300 minutes for 30 days.
The smartphone runs on a Qualcomm MSM7227 SoC clocked at 600MHz, comes with Android 2.1 with SE's Timescape UI, has a proper slide-out QWERTY keyboard with 128MB RAM, a 2.6-inch capacitive touchscreen with QVGA resolution, a five-megapixel camera, microSD support, A-GPS, Wi-Fi, Bluetooth and ActiveSync compatibility.
The new Xperia Pro builds on the X10 Mini Pro by offering a bigger keyboard, a more powerful Snapdragon SoC clocked at 1GHz, a much bigger screen with more than five times the pixel count, a newer version of Android and support for bigger microSD cards.
