Grabbed some hands-on time with Samsung's i830 smartphone—and had trouble putting it down. It's a quad-band Windows Mobile unit outfitted with EVDO. It has 64MB internal memory / 128MB Flash and an expansion slot. The screen is 2.8-inches and 65K color TFT, touch-sensitive too. Slide the 5.2-inch top vertically to reveal the full QWERTY keyboard. The keys are a bit smaller, I think, than the ones on the Treo 700w. The i830 is a bit thinner (.6-inches) and the same weight (6.4 ounces) as the Treo 650, but it lacks a camera (!!) and has a slightly lesser screen at 240 x 320 pixels. But if I was considering buying a Treo 700w, I would take a serious look at the i830 first. It's available January 12, pricing TBA.
I had mine for 8 months and I'm selling it. Great features but several FATAL flaws. It is a power hog. Battery life stats are way off. Can't last a day on standby. Windows OS is very unstable. It crashes once a day or every other day. The soft reset is ok. But if you let power run out, or have to do a hard reset, it loses everything and then syncing gets your data back but it doesn't get back your blue tooth paired devices or your wireless email settings. All have to be redone (and it can't be done on the computer and downloaded).
