While nothing here solves Blu-ray's number one problem, price, there's no denying Sony's got some fun tech on display in its new 400 disc Blu-ray MegaChanger and the new BDP-S1000ES single disc Blu-ray player with WiFi. The MegaChanger presents a lovable XMB-style, Gracenote-powered onscreen menu for sorting through all the media stashed in your MegaChanger, and the S1000ES packs in 802.11n for BD-Live, along with premium analog outs and some dashing good looks for the well-heeled enthusiasts. $1,900 and $700 of respective awesomeness? Well, that's up to you decide.Gallery:
