My biggest gripe with the Pi is a lack of proper USB power, so if you add all the stuff you need, especially for a wireless setup it's not so cheap and compact anymore. I'm happy that they've (hopefully) fixed the USB power problem, that makes it much nicer as a platform.
I've been providing power over the GPIO header directly, and have had great results. Combine a DC-DC supply with a few smoothing capacitors on a small daughter-board, add a barrel jack + 0.1" headers to interface and you get a lot more headroom and flexibility with how you power it.
(Same-ish end result as the other fuse bypass methods, but with no soldering on the pi, and the caps seem to help with the inrush current required for hot-plugging USB devices. )
It's a tradeoff vs device safety, but is super cheap, and the operational reliability is worth it for me. Every time I stage a pi for a project that isn't powered this way, I'm surprised how much frustration is involved.
Looking forward to this improvement with the B+ as much as anything else.
