I upgraded from the x50v (of which I was a very early and satisfied adopter) to the x51v because I thought Windows Mobile 5 would improve things like bluetooth and Wi-Fi capabilities. They fixed the Wi-Fi security compatibility, but Bluetooth has really, really fallen off the wagon. Before Dell included a Broadcom bluetooth stack, and it allowed me to do things like upload ringtones (in MP3 format), and download pictures from (in JPG format), my Motorolla v650 and v505. Get this: I could even context click an entry in my phonebook and have it dialed on my phone, connected in turn to a bluetooth earpiece (in addition to GPRS). Now they use Microsoft's bluetooth stack, and all I can do is dial through GPRS, which *is* the most important bluetooth feature, granted (at least for me), but should be just the beginning. I mean, what about stereo earphones, ObEx, PAN etc.? There's a rumor going around on AximSite.com that the big MS is working on a new stack, and all I've gotta say is that they'd better do it fast, or there will be a large client and vendor base who are very frustrated with the folks in Redmond. Guys! Just buy Broadcom. You'll still have enough left in your wallets to buy lunch.
I've been looking at buying a Dell X51v and some of the reviews are mixed. One major thing for me is BT. I have a IPAQ h2215 now and it's a little weak - have to reboot a lot. But heard some good things about the Dell. I'd like to be able to BT dial my phone and connect to my BT GPS receiver. Do you think these are going to be issues for me (I read your message)?
