I don't disagree - but yet, the statement IMO was bit too generalized because every decent MFX unit is delivering almost outstanding quality and diversity at bargain prices.
I for one defenitely don't need all that stuff (neither the amount of amps, FX and/or their quality) for my daily needs.

And fwiw, if I was to spend some decent money and wanted to sound "not the same", these days I'd rather buy a Macbook Air, a decent interface and a MIDI controller. That would actually give me the most amazing portfolio of amps and FX ever. Add to this instant guitar-to-MIDI stuff, if I felt like doing so.
In fact, it's something I'm seriously considering, should I ever want to go for something truly advanced, the only real issue being that I just love to have a single floorboard suiting all my needs, something absolutely impossible with a computer based setup (I know, there's some adventurous folks slapping a Mac Mini onto boards and remote controlling them via iPads - but that's nothing I ever wanted to do).
I will defenitely give that another thought next year. One day I'll have to buy a new Macbook anyway, so I could just do that earlier and use the current one as a live machine. Soundwise, it'd likely mop the floor with any of the current all-in-one modeling offers. NAM captures, Tonex captures, the wildest dirt FX (the Eventide CrushStation alone is worth considering that route), incredible delays and reverbs, etc. There'd also be close to no limitations regarding FX amounts. I can run at least 3 fully stuffed HX Native instances on a single core. That'd make 12 on 4 threads.
And once the initial setup would be done, it'd also be a dream to control as anything would be possible, such as a tablet running TouchOSC wirelessly connected to your rig. Add some quick access MIDI knob encoders and bob's your uncle.
It would mop the floor for amp simulation and effects. The weak point is the foot controller. Using midi, it would be difficult to match the useful interactive footswitch features often found in floor modelers or dedicated foot controllers (scribble strips, color encoding, syncing when loading presets, etc.)
