Well, after putting up with my PPC-6700 for nearly a year, I finally had had enough tonight. After my 6700 wouldn't let me make any more phone calls because "I didn't have enough signal". Of course, while I was getting this message, the phone had a full four bars of signal strength reported. Well, that might seem minor, but given the track record I've had with the phone I decided it was enough. Off to the Sprint store.
Amazingly enough, they actually had the Treo 700wx in stock, so I picked one up. So far I'm in love with it! It's about 1/3 smaller than the 6700, and while the screen is smaller (240x240 instead of 320x240), I'm rapidly adapting to the way it works. We'll see how I feel about it in a week, but thus far I'm impressed.
