Here's a fairly interesting
article about cellphones, convergence and disappearing profit margins (via
Slashdot), and an even-more-interesting (well, to me anyway)
article on Gizmodo about eBooks, barriers to adoption and DRM (via
Library-Link-of-the-Day).
That said, if you just want to know what cellphone to buy, you might try
Phonescoop and/or
Mobiledia.
