As another comment mentiones together with a mitre saw and some jigs i think you could replace a table saw functionally, but its probably not the most efficient way of doing some things.

With a track saw and a miter saw, I think you can say "I can crosscut, miter and rip." But I don't think you come close to matching the capability of a table saw.

I think a track saw really comes into its own when handling large panels or slabs. If you hand me one of those 2 inch thick slabs you're making one of those trendy river tables out of and tell me to cut the live edge off of it and square it up, I'm not going to even try that with my table saw. Same with cutting some arbitrary diagonal line across a sheet of plywood.

Your average sliding compound miter saw is quite convenient but I don't think as good as a table saw for crosscuts, miters, bevels or compound miters. Now mind you as a carpenter I'd happily show up to build a house with my miter saw and a normal circ saw and leave the table saw at home, but for woodworking I want extra accuracy and precision that I can get from a table saw and a good miter gauge or sled.

Things I think you would struggle to get done with only a miter saw and a track saw (or: why you're probably going to get a table saw)

• Ripping boards narrower than about 8 inches

• Resawing

• Non-through cuts such as grooves, dados, rabbets and tenons

• Multi-purpose jigs such as taper jigs, sleds, tenoning jigs, panel cutters and the like. Try tapering table legs with a track saw. Actually don't.

• Job specific jigs and fixtures are possible but less useful.

• Coving. If you haven't seen this done go check out a video of someone cutting a cove with a table saw. It's a hoot.

Not to mention that table saws are just more practical to set up for repeated operations/batch work
