A 500 gigabyte hard drive and Wireless-N connectivity represent the yin and the yang of the system's hidden insides. We'd much prefer more storage space on the former, but we appreciate that the latter allows us to solve the issue of the Omni 100's paltry wired networking speeds. As mentioned, you can upgrade the optical drive, hard drive, and memory of this all-in-one. We appreciate that HP's all-in-one (unlike most others) at least gives you the option -- and the printable instructions -- for a little internal modification.

Oh, and remember a bit ago when we said that the Omni 100 comes with six USB ports for connections? In reality, you can knock that down to four: An included wired mouse and keyboard, both generic, reduce the meager connection offerings of HP's AIO even further. You'll at least have the option for purchasing wireless peripherals them online.

At some point, a company can only strip so much away from a desktop-or all-in-one-before the little joy it offers completely overshadows whatever dollar amounts you're saving in the process. In the Omni 100's case, spending just a bit more can get you quite a bit more machine, whether you're looking for touch functionality, or more power under the hood.
