pittsey is the truth. that is the way to do things, because so many things look good on paper but using the device is completely different.
generally, i would shortlist devices i want and would probably buy - but i;d always check reviews and check it out for myself (if i can). most of the "get an iphone 5" comments come with the notion that iphone 5 will be the 'latest and greatest' because its a no brainer that it'll be better than the iphone 4.
most of those people forget that the reason the iphone seems so popular is because its one device, as opposed to the lineup of entry-level, mid, upper-mid and high spec phones from other manufacturers. although blackberry has different devices, there is one sole manufacturer (blackberry) that uses RIM in mass.
