"I really wanted to like the EX495"2.0 starson by rayman1963
Pros: + Operating system never crashes
+ Hardware seems pretty stable/reliable
+ Good overall system performance
+ Expanding user base and add-ins are attractive
+ Support for Mac Time Capsule backups
Cons: - Included software is horribly unreliable: Twonky media server software just quits, the "automatic" conversion of decrypted dvd's fails repeatedly, the iPhone streaming doesn't work
- HP infrequently updates software
- Limited to 10 devices
Summary: I have a mixed network environment, with 2 Macs, 4 PCs, Sonos sound boxes, xbox, Wii, PS3, iphone, and ipod touches. I am using the EX495 to centrally store and manage our music/video content and perform all backups. The "value added" software that is included is, unfortunately, rubbish (with the exception of Time Capsule backup). I have tversity running on an old XP box that is WAY more reliable than the flaky Twonky software, which rarely gets updated by HP. The iphone software never seems to be able to connect, my Bravia TV can't get the DNLA feed from the EX495 (but gets it from the TVersity box), etc. It is hard to get online support from HP, and they don't make it easy to contact them. I really like what Microsoft has done with WHS, though, and I do like the TIme Capsule support. My Sonos boxes can now read from the server and stream music flawlessly. Speed is overall good. The rubbish McAfee antivirus does not download updates and needs to be removed.
Overall, I had high hopes, but came away disappointed. Don't waste your money on the HP box until they fix the software. Windows homeserver rocks -- I would recommend buying one. Find good third party solutions for Time Capsule support and for Streaming video, forget about the iPhone stuff for a while, and you will be happier.
