Charts
    I got to wondering about producing a lifespan chart for the different portables and came up with this. This only includes those portables that were in direct competition in the US. It is not really completely accurte because it does not include when the products entered or left the marketplace. For example, the Neo Pocket Color really only had about 13 months on the shelves here in the US. The information was the best I could do for now, I am thinking that it is close to being accurate. It is really only made to convey a general idea. I feel that some things did overlap at points if only to sell out of old stock. For example, right now the PSP lite is on the shelf while the PSP is probably no longer in production and the last ones will shortly be gone.
