There's no denying that HTC's Advantage X7510 fills a narrowing niche -- after all, how many of these things have you seen out and about in the subway / underground? Still, there's just something very enticing about a 5-inch VGA display, built-in GPS, HSDPA, WiFi, Bluetooth and a full-blown QWERTY keyboard, is there not? For you folks who plunked down quite a few bills in order to bring this home, how has your experience been? For you folks in America who have just recently decided to bite the bullet and jump in, was it worth it? How would you tweak this do-it-all conglomerate (besides making it way more affordable)? Here's your shot to get it out, don't let it pass you by!
