"I chose this over the Eternity"4.0 starson by regaug
Pros: Touch screen is fast and responsive, better than the Eternity
Build quality seems excellent; leather-like non-scratchable back
Music player sits in memory making it easy to stop/start with bluetooth
Small and light for a touchscreen
Cons: Wish the widgets were customizable (like adding new ones)
Wish they hadn't downgraded the camera res (only thing that is better on Eternity)
Learning to scroll on the touchscreen takes some real practice
Memory card sits behind battery (nit pick)
Summary: I disagree with a lot of CNET's review; this is a solid, nice phone. I chose this over the Eternity and LG's VU because it seemed to have a better quality build, and seemed less "clunky". The Touch Wiz interface seems more responsive on the Solstice; that and the vibe feedback make it much easier to text with, IMO.
I chose this over the Impression because it was cheaper, lighter and smaller, and after trying them both out in the store, I decided I didn't want the slide-out keyboard. I learned to txt with predictive T9, and I can do that faster than use qwerty with my thumbs
I did not compare call quality between the Impression and Solstice; but I have read several reviews complaining of call quality and especially speakerphone echo problems on the Solstice. My phone does NOT have these issues, call quality seems normal, I am told it sounds just fine on speakerphone. On my end, the quality of the speakerphone is not quite as good as my trusty old LG CU500 music phone, but acceptable considering I usually listen to music via bluetooth.
