I have heard today that there may be a T4 on the way possibly with Wi-Fi and BT; If I decide to wait and see if Palm does release something new this fall, I need an upgrade from my i705 now.
For use while I am waiting on the "big new one" would a m515 or a TE be the best buy - or something else?
The TE is a better choice: much faster processors, doubled the RAM, and all around better device. One except though: it doesn't have an universal connector. So if you can't live without a current accessory that utilizes the UC, then don't buy the TE.
