I've been using the Mogul for about three months (see my recent post on woes regarding use of the device as a phone on the "Who Has a Wing/Mogul thread).
I aggree with others that the device is SLOW - even compared to my old X30-Hi. Running Pocket Informant with about 600 contacts stored, it takes about 5 seconds to filter contacts for a search. The same app with the same contacts list running on the X30 would do it in less than 2 secs.
BUT - I have to concede - using the device as a cellular modem works great. With EVDO bandwdth, download speeds are surprisingly fast.
E-mail (I use On-Demand - not Push) works fine too.
The built-in keyboard is good - but so many times, I still find myself reaching for a stylus and going for soft-input (too many years of Palm and Axim habits I guess).
But if I'm going to compose a long E-mail or Text Message, I have found myself gradually learning to slide that keyboard out.
I just wish the device were more reliable as a cell phone...
