Since this app lets you go through one operating system to access another, you can expect a few minor issues. Here are some things to consider, but they should in no way deter you from checking out this software.
Your PC Must Be Turned On
In order for this to work, your home or office computer must be turned on and have the Splashtop software running. If your computer is in a power-saving sleep mode, it won't work. This can be a concern because keeping your PC running full blast all the time can cause it to wear out more quickly.
Network Speeds Vary
This software only works over a Wi-Fi connection, so unless you have a wireless network to connect to, you won't be able to make it work. This means you won't be able to access your PC while driving down the road, and I think the main reason for this is that cellular networks don't have the proper bandwidth and throughput to allow this software to work properly. If you use this on the wireless network in your own home, then expect the performance to be perfect. On other networks, such as public places where you might be sharing bandwidth with many others, the performance could fluctaute greatly.
Windows Interface Woes
If you plan to use this software often, you might invest in an iPad or iPhone stylus to make interacting with the Windows OS much easier. The reason for this is that Windows was designed to work with a mouse, and those tiny little boxes and small text menus might be tougher to click on with just your finger.
