I got this phone about a week ago and I love it. It's a great size and weight (similar to an ipod classic) and the colour screen is really sharp and clear. The drag on drop feature on the widget screen is really fun and different from other features on phones out there.
I thought i would struggle with the texting been a lad with fairly large fingers and at first i did struggle but now it causes me no trouble at all.
Overall the phone is really well made and the touch screen doesn't slow at all and hasn't caused me any problems. It isn't an IPhone beater but it doesn't matter. It is still an amazing phone. Well done Samsung!
