David, very few tables are perfectly flat. Having the center slightly convex will have no noticeable effect on your projects. Concave table tops are where the real trouble comes in. With the center slightly higher than the sides the wood will pass the bit at the same height every time. The real question is how much measureable distance is the table off from flat? For routing applications 1/16" over the length of this particular table top would be too much, 1/32" would be ok. This is something all manufacturers have to deal with, none are 100% perfect. Even the pre-stressed cast iron tables can be warped in shipping. The good news is Bosch has shown us they stand behind their products and will make sure it works for you. If you have problems with this table PM me and I will assist you.
