During my brief period (so far) in the cell phone insurance industry, I have learned one indisputable truth. The RAZR phone is a piece of horse poop. If you buy one, expect it to do two things well: fail and suck.
Also, I provide you all with this sound advice: Do not buy first generation models and expect them to work well. The LG VX8300 has been on the market a short while and it's stench fills my nostrils from every call I receive from owners.
Most importantly, the more components on your phone is directly proportionate to how much breakable crap you have in a cheaply made plastic device.
My recommendation is if you need a reliable phone, do not buy one with an MP3 player or video camera, unless you really want an expensive barrel of ass. If reliability is an issue and you need a PDA and a phone combination, by all means get a Treo, they break consistantly. In that way, they are reliable to a fault.
If you don't have the money for a seperate PDA and cell phone then you probably don't need a PDA.
Finally, if you absolutely must have the most amazing gadget-infused mobile phone on the market, treat it like a faberge egg. Your warrantee does not cover physical damage ("I only dropped it once!" doesn't buy sympathy, but will instead garner you laughter at your expense), liquid damage--including exposure to high humidity, (don't take it in the bathroom while you shower, don't put it in your pocket when it rains), or even damge caused by heat (don't leave it in your car in the summer). As a matter of fact, you can have liquid damage by leaving it in your car during freezing weather (remember, the L in LCD stands for "liquid").
In fact, don't take it anywhere. Thanks to shoddy craftsmanship and a worthless warrantee, it's no longer mobile and it's hardly a phone.
