Pros: Very good sound quality. Better menu system than previous year models. Very good network features. Parametric equalizer and many audio tweaking options. Internet radio, HD radio

Cons: Remote control! Yamaha used to make better remote controls five years ago. My RX-V2500 that was cheaper and had a nice lighted remote. But this one is clunky, hard to press buttons, no back lighting. Almost useless LCD screen. To make things worse, they have some buttons under flip door. Come on Yamaha, we need a better remote control! Missing THX features. Video settings are pretty nascent (just a scale of 1 to 6, quite useless especially if you have a good Blueray player.)

Overall Review: iPhone app is an excellent value add and has more functions than Denon or Pioneer. Nice web interface suitable for tablets and smart phones, even if you don't have an iPhone.

Pros: Very good form factor, expandability, standard iterface, gigabit ethernet, low power consumption, remote (web) access.

Cons: Media collector is quirky and needs baby sitting. I had strange errors with networking and .net. Challenges with interacting with Windows 7 out of the box. Huge disappointment with HD video streaming to PS3 (at least I wasn't able to make it work)

Overall Review: May be I should wait for the next version of WHS (Vail?). This one is going back. For $600+ price, HP could have thrown in E7xxx cpu which is still 65W instead of E5200. I wish Microsoft would combine WHS with Media Center PC so that it would be part of Home Entertainment system with a TV tuner / Blue ray, etc. I would like to reduce the redundancy of having multiple computers.

Pros: Works without any issues with my Lenovo T510, even when added to existing RAM from another manufacturer. No crashes or BSODs.

Cons: None

Pros: No issues at all with my T60 Thinkpad

Cons: None

Overall Review: Ironically my T60 only recognizes 3GB max. I am stuck with it for now.
