What do you use to detect mobile device attributes?
Starting with this forum's stickies, I eventually ended up buying "Programming the Mobile Web" by Maximiliano Firtman. His chapter on detecting the device and mobile screen attributes (CHAPTER 10 Server-Side Browser Detection and Content Delivery) is , um-m-m, daunting to say the least.
"All" I want to do is determine if the device is mobile, the screen width and assure that the font size is readable. Firtman gets into Ajax and WURFL and/or DeviceAtlas as his recommendations for device / format detection.
Is it really that hard?
