This is second touch screen phone (previous LG Viewty useless - was a couple of years ago). I have been using ordinary Sony W890i and found transition very easy.
The internet access appears very quick and setting up access to your email accounts is very quick, I didn't even need the manual. Friends say they can hear me clearly and much better than previous phones.
The only niggles are when texting you can press the send button without finishing text especially, if you use higher and lower case, but this could just be me getting used to the touch screen qwerty key board.
The other thing that is really annoying is the contact list has seperate entry for first and last names no problem until you save or use your existing contacts. So if your last phone didn't it assumes or reformats assumning all your contacts are first name and adds forward slash and / or numbers for no reason. This means contacts are all over the place and not where they were on previous phone, this may be just a Sony vs Samsung contact issue, but annoying as you have to go through and change all the contacts. On the plus side copy and paste is fairly easy and saves time.
In all other aspects this is a good phone. Build quality appears good and solid. Not checked the Samsung Apps store far, but appears limited, but if you are not interested in android apps, go for it.
PS I haven't tested camera or music player, but as I have DSLR and ipod not really bothered, will add comment if I test it out. I will be testing radio this weekend and will amend this then.
