Palm Centro – one device to rule them all
I've considered before trying to "converge" all my various tech devices into one device. I had previously melded my previous PDA and my iPod into just the Palm TX, since it does a great job (for my uses) as a music and video player. I've always thought the Treo was too big for a phone, and didn't compare to the quite large screen of the TX, which is great for viewing videos in widescreen format. I have been using my TX daily at work to listen to several Podcasts a day, and to watch downloaded TV shows on it while I'm on the bike or treadmill at the gym (the only thing that's successfully convinced me to stay on a treadmill for 45 minutes).
As soon as I heard about the Centro, it intrigued me like no Treo ever had. It would allow me to combine my phone, PDA, and audio player into one device that is just barely larger than my current flip-phone. It will still work with my Bluetooth Stereo headphones, so I won't have to dodge earphone cords all day while listening to my podcasts.
The only real tradeoff will be having a much smaller screen, especially being used to the extra screen space the TX allows. I'll probably still use the TX for video watching at the gym, but otherwise, I'll happily have one less thing in my pockets.
