Well been using this in the Bay area, and so far I am very pleased. It's download rates are actualy faster than alot of DSL speeds I've seen, but uploads are still slow. Still good enough for most applications. Setup was very easy, though I had to download the driver and connection management tools directly from Sierra, insted of being able to instal off the CD, something I hope they fix in the next version. The 595U, uses the qualcom 6800 chipset, wich is rumored to be upgraded through the next revision, and features Dual-band, 800 and 1900 MHz, and a built in GPS antenna. So far this is what I've experienced. Apple Remote Desktop and VNC: Not bad, a little slow on the connection, latency definatly hurts, though the lag seems to decrease once a connection is established. I suggest running the screen in black and white. Other than that, it's not bad. I had no drop outs or problems with syncing up. Streaming audio download, iTunes: Seems to work great. Driving around will get you dropouts in some spots, just like any other cell device, though I had only a few spots where it had to rebuffer the stream. If you can tolerate 64kbps down that seems to work best, but 128kbps is tolerable with only a dropout maybe every 10 to 20 minutes that clears up quickly. This is particularly good for me, considering that bay area radio stations suck ass. Apple update: Again slow at first, but downloaded the files (security patch and iTunes update) faster than most DSL connections I've used. Web browsing: Fast, particularly for any site that doesn't require alot of information to be uploaded, though posting on OT is still quick. In fact OT only slightly lags with this, compared to DSL, and cable. speeds seem consistant even when testing various locations. Even though I have an unlimited data plan ($48/month) I wouldn't use this as my primary internet connection, but it's nice to know that for the most part it could, in fact it outperforms my landline broadband service from just a couple of years ago.
