That's pretty much the case for the G Tablet. I own one and have been involved with the modders over at XDA since they first came out. I can honestly say it's a real whiz BUT there's not a lot more we can do with it without source code which Viewsonic doesn't seem to be too willing to release. The dual core Tegra 2 is a screamer, the 512M RAM, 16G built-in storage, the microSD card and the full-size USB port all make for some real potential, only some of which we've been able to unlock with custom ROMs. But, if you aren't interested in modding, perhaps the Archos is a better bet.
