HP claims that better engineering and customer service are differentiating it from competition
HP iPAQ hw6915 has built-in Wi-Fi (but is not so widely used because unlimited flat rate mobile Internet access is available)
using free Wi-Fi from Motorola at CES
rx5900 is a Pocket PC PDA but it can also be used as regular GPS navigation
Conclusion: since HP iPAQ hw6915 is based on the same hardware as HP iPaq hw6515 one could say that since several years HP has not released new Windows Mobile phone. iPAQ hw6915, compared to contemporary competition, is a bit over-sized and also lacks 3G (neither UMTS nor HSDPa is supported, only 2.5G: EDGE), but anyway HP is big reputation and trust of customers in USA so Cingular customers may be interested in this handset!
