If I could walk into an Apple store and get one with a memory upgrade I would do it in a heartbeat. I have settled and purchased many base models (although wanting the memory upgrade) just to avoid ordering online. I suspect I am not alone.
Okay, yes you aren't alone in this opinion, though you are still wrong. Apple knows their market and hence try to capitalize on this by stocking products that WILL be sold given a certain products life cycle.
The people that do want the upgraded memory aren't gathered together in one market for them. So you are telling Apple to ship an adequate supplies of your 8GB model to all markets. This causes Apple a raise in cost for shipping, loss of valuable retail space to stock other (more popular products) and lastly manufacturing cost.
You have to keep in mind how things are manufactured as well. The reason the 8GB model is BTO is because they have to switch parts on the assembly line causing them to create less 4GB models and hence reducing overall profit margins. This is one reason why Apple products are so expensive for BTO, that and Apple wants to keep it's profit margins on the product.
There is a reason why Apple waits so long to ship the 8GB models is because they wait X days gathering all the BTOs as they can in a reasonable time, then make the BTOs and ship them. After that, they build one set of BTOs, they wait until they get an adequate amount again because they go back to making the base model (the biggest profit margin for them because they are making MANY of ONE type of unit which reduces cost of manufacturing).
Basically you are telling Apple because very few people ask for the upgraded memory they should still just make these products and ship them to a store where all this does for Apple is increase their product diversification, increasing costs of production, increase shipping cost and lose valuable retail space.
It's ALL about maximizing PROFITS when considering manufacturing methods and costs. Hence why there is a BTO option. Get over it, us (ones desiring MORE) aren't the biggest money makers for Apple and that the standard Joe and the base models are.

Due to the tax arrangements in the UK / Europe we face additional time if we wish to return the product within the 14 days period due to a fault etc. If bought BTO online, the item cannot be returned in store. It gets sent back to Apple Onlne which takes 7 - 9 days to process, then another 9 - 11 days to get a replacement BTO machine.
Really? Here in America Apple Retail Stores will return BTOs and refund you. They cannot exchange for another BTO as the retail stores have no access to this.
Also, once you do get your BTO replacement it restarts the 14 day return policy.
