the tilt does have a gps chip and support for sdhc.
as far as wich one to get, well do yo want 1box or 2. also windows mobile6 is alot nicer than the previous versions of the os. lots of improvements. dont forget triband umts/hsdpa plus wlan b/g.one more thing to consider- for watching video/movies etc the tilt is missing grafix excelorator(theres a class action lawsuit against htc for this ) from what i've read it makes watching video not a nice experence.
