For me the preamps in the Toneport were neither clean and transparent, nor rich and warm. They also didn't have enough level for some of my microphones. I ditched it quickly and traded it for a Pod X3. That gave me Gear Box, Pod Farm, great guitar modeling, and at least as good a soundcard as the Toneport. Now I mount it in an Atomic Reactor amp, and use an FBV mkII as a controller. That gets me some more life out of a legacy product.
The number of I/Os was also a limitation, and it never worked glitch free. I actually only wanted to use it to get guitar sounds into Sonar because my Pod XT was being used for my live rig. An Echo Layla 3G still serves as my audio interface, and that is probably the longest lived device in my studio. Computers, monitors, plugins, effect devices, midi controllers, pitch to midi converter, and more have been replaced because of the upgrade cycle in operating systems and DAW software.
That is why I warn others about making purchases without considering longevity. Some equipment is long lived; others a flash in the pan. I got caught badly by investing TC Powercore and Focusrite LiquidMix. A bundle of money down the drain that I wish I had invested in a really good stereo analog compressor. I know better now. It is sad but a good amount of ill will towards those companies is associated with their financial decisions to abandon these products. I just don't trust them any longer, and won't purchase products from them. That is the best way I can respond to such practices. Now I am much more cautious with my purchases, and realize fewer tools more aptly applied leads to quicker and superior results. I also save a great deal of time that was formerly spent learning new products, and integrating them into my studio, along with the frustration that goes along with it.
