[Acer Iconia A500] Neoprimal:
It was a choice between the Acer and Asus for me. I got the Acer because I was impatient, but I ended up not returning it because after using it I couldn't see myself getting by with no usb and no flash. I considered the new Galaxy Tab as well but for the same reason I decided not to wait.

If I DID end up waiting, I'm sure I'd have decided to wait for a Kal-El based tablet. At some point in the 'waiting for better to come' game, you have to take a step or you'll never buy a product. I use the tablet daily, even my wife uses it now and so it's proven it's value to me.

I use the flash for extremely stupid things, but tbh to each his own, right? One of these things is to sneak into bed at night. By the time I go to bed sometimes my wife is already sleeping and she's a very light sleeper. Flicking a light on to see where I'm going would surely wake her up and it's sometimes difficult to navigate around the bed (without smacking off a big or little toe). I thought, "can I live without the flash? Sure!" But it would be an inconvenience, especially if I do ever find myself in a slightly more important scenario where I need it and don't have (for taking a pic in low light, for eg).

The USB is a must as I travel a lot and the big reason for getting the tablet beyond using it in my home is so I can travel light (without having to use my laptop). With the usb I can plug flash drives or hard drives in and watch my tv series and movies or use it to juice my phone if I strain it chatting too long or whatever.

Other than that, I didn't like the feel of the Transformer and I didn't want to depend on getting/using the keyboard part to have usb functionality. I had been keeping up with all the pics of the light bleed and saw it first hand. Who wants to worry about getting a tablet with light bleed at a time when they weren't in very many stores? That would have meant back and forth shipping. Not my thing.

The Acer is fully usable as-is, with the Asus and Samsung you MUST buy accessories for them to get a usb port.

I also considered resale value, like any tech head :). If I am to resell my Acer A500 right now, I'm going to get ~$400 for it (not everyone knows about the sale price of 350 at certain stores). In a few months, I will lose another $50 to depreciation...as by then I'm sure the price will further fall to something more attractive to fringe and impulse buyers.

The Samsung with added accessories to make it function similarly to the Acer is already in the $550 region, but it will depreciate exactly the same as the Acer, unfortunately. Same with the Asus.

So after you buy the accessories to get USB (if you need it), you still end up selling the other tabs (with accessories) for approximately the same price as the Acer, as resale value for accessories is little to nothing and you can very rarely if at all sell them on their own. (This is based on the many, many times I've seen people reselling their tablets with accessories like docks and cases for way, way less than what they got it for).

In essence, you lose more money with the other tablets IF you need* to accessorize them. *(to play catch up to the A500, like buy the keyboard section for Asus or buy the proprietary addon for the Samsung to get USB)
