Hey, I'm new here, and also new to smartphones. I was told to read up on this site to learn more about them. I bought a Behold II a couple days ago and its awesome. Now I realize its my first smartphone, so its probably in actuality not as awesome as I think it is, however I have spent plenty of time playing around with my friend's G1, and also a lot of time with the Cliq. So while this is this is the first I've ever owned, its not my first smartphone experience.
As for mateo2, its unfortunate that you had all those problems with the phone, but I've had it for about 5 days now and have not experienced all the problems you did. For instance, the app drawer has yet to lag in the 5 days that I've owned the phone. The home screens however do lag for about the first 5 seconds after you wake the phone up. This can be an annoyance to some, but it really is only about 5 seconds or so, and then its gone. I mean I can live with it.
Also, I disagree about the music player, I think it is much nicer than stock Android, the only problem is that the cover art doesn't transfer. It does on some, but on most it doesn't. So, hopefully there will be an update soon to fix that. I'm not quite sure what you're talking about with not being able to get back to the main screen by pressing menu. If you mean the home screen of the phone just hit home. If you mean the main screen of the music player you just swipe left or right.
Also, as someone else has said you are misinformed about the update, it will get updated to 2.0. Samsung has the update ready and is waiting on Tmobile to release it. It is mentioned in passing in the review or preview by Cnet I believe.
Contacts can only be searched by first name which may be an annoyance to some, but not really to me.
Also, the keyboard is much better than the stock Android's I have used. Some people have reported a lag that can be fixed by turning off the vibration feedback, I haven't had it lag noticeably yet though. The keyboard IS difficult to use in portrait mode however, so someone might want to get a keyboard replacement because of that. I only find that its difficult when I'm trying to do other things at the same time, like drive, so I'm going to keep the keyboard so I don't text and drive anymore lol.
The camera is the best I've seen on a phone. Better than the Behold my girlfriend has, better picture than the iPhone that my friend has (although not as quick), better than the Droid (from the short time I had with it, and also from reviews that I've seen of it). The flash can be too bright at times, but some time with the camera and you figure out how to work it properly and the pictures are really quite amazing for a phone.
If anyone has any questions I'd be happy to answer them the best I can. Like I said earlier, I'm not as smart as you guys when it comes to these devices so you might ask me something that I have no idea how to answer haha. But, I plan on reading around this forum over the next couple of weeks to expand my knowledge. Hopefully it works, and I can root the thing without breaking it
