What is the best smartphone to buy? Permanent 4 aka Dave is facing that question and he brings up some very valid points. Well it is a relatively personal decision, and despite a large number of choices, I think it boils down to how and where you use your smartphone. I am perfectly comfortable doing text messaging and email on a Nokia 6620 and hence prefer that over a say, Treo 650. However, others like Pocket PC phones. For those of you who desperately crave a keyboard, and use windows, but don’t do email more than once or twice a day, I think Nokia 6620 paired with a Pocket PC device with keyboard is a good option. For others who are heavy users of email on the go, I recommend the Pocket PC XDA and its many variants or if you must, get a Treo 650.
