The Incredible S is a bit of a confusing phone for me. Its 4" screen sits right between the Desire HD (4.3") and the Desire S (3.7") but everything else about the phone is identical in specs for the other two. Its one very subtle market segmentation.
I just wonder why HTC did it but I guess the Droid Incredible has been such a successful phone for them and Verizon that Verizon ordered a successor. Then HTC decided to cash in more on it by creating a GSM version.
If you already have the Inspire the Incredible S is redundant.
HD7S is another old tech phone.
