How about no? Making it 10MB would just necessitate another hard fork in the future. We should have as few hard forks as possible, so make it dynamic somehow so that that part of the protocol need not ever be changed again.
One of the key elements of Bitcoin is decentralization via the P2P network. Average Joe needs to be able to run a full node. In my opinion 10MB blocks (some 100MB per hour) are acceptable for average Joe these days, but 100MB blocks (some 1GB per hour) are bit too much now (maybe ok in 1-2 years). Unfortunately there is no reliable indicator for Bitcoin to know what are current network speeds and hard-disk sizes. If tying it to past results, big miners could game such system. I can't see any good dynamic solution. Imho if it can have one hard fork now, then it can have another after 1-2 years. Everybody understands what replacing 1MB with 10MB means, it's no rocket science.
