Treo650 vs treo600

Since I bought Treo650, more than 2weekss has been past.
What's new to compare with ex-main machine treo600?
As above, Treo650 has high-resolution screen. So especially for Japanese language, it is more beautiful than treo600 (low-resolution screen).

At first, I could not find out 650's turn on button. Because 600's turn on-off button is located at the bottom of antena. On the other hand, 650's is one of hard button(Keep Long push).

Side Button is also changed. Treo650 has additional back button. But its surface to too smooth to key in, then some time easy to drop.

Regarding graving, 600 has inmold-rubber at the corner, but 650 has nothing like that.

The shapr of stylus is changed. When we need make reset, treo600's stylus needs to take out it's head, but Treo650's is no need to take it out, Just push the reset button. But the location of 650's reset button is difficult to push. You need to take out battery cover and push(The hole upper side of battery).

How to insert SD is also different. treo600 make you upside down SD card when you insert it to treo.But for Treo650, it's quite natural. No need to upside down, just insert it as usual.

Of course, you have many chance to use Treo outside, because it's mobilephone. But treo600 screen is difficult to see at outside. On the other hand, Treo650's is improve so much. You can recognize what's on the screen easier wherever you are.

Your first impression may these two models are same. But there are so much improvement on Treo650.
