Does anyone have experience with the streaming performance/battery life of Maxell's AirStash? At 320kbps only about half of the bits(pun!) of my collection that I want within reach (~60GB) will fit on the iPhone 4. My goal here is to get as much storage as possible in as few components as possible... and fit it all in one pocket if possible. Seagate Wireless Plus and Patriot Gauntlet Node seem like outstanding solutions where size is slightly less of a restriction. Looks like unless reverting to a Clip+/iPod Classic/Cowon X9/etc most of this new tech may need an almost-daily charge, but I'm willing to compromise for the features involved. This is an ultra-portable rig, not a mini-audiophile solution. I haven't yet tried out the iPhone's battery with Wi-Fi continuously in use though - reputation is that it does 4 hours nonstop but I will have the display set to minimum or off while listening.
If anyone has an estimate on iPhone 4(not 4S) with WiFi full-on but display off I'd appreciate it! - phone functions off while using as player...
Clip+/MicroSD-to-SD/128GB card would be my next choice of hardware...the price on that setup is low enough I might could get it as a secondary for longer durations without charging. - looks like under $100 without the card!
