Why? It has sold equally much software (well, will), and it will definitely make more money.

its almost their

 But from a revenue perspective handhelds are a lot cheaper and thereby easier for people to purchase.

I dunno, for some reason I ignore handhelds sales almost completely. It's as if they don't count, in my world.

yeah i rememeber getting my first ps1 i think my rents paid about £270 one xmas for it, so it isn't fair to compare and recently i bought a ps1 in cash generator for £5:99 alllright giggity giggity goo , but yeah well done Nintendo that's an awesome number of ds's

They may make less revenue, but then again they also cost less to produce as well and revenue does not equal profit. For example, comparing the PS3 to the PSP. Let's say they both sold the exact same amount of systems for the week. The PS3 costs several times what a PSP costs, so the PS3 would have a really high revenue; however, the PSP makes more profit for Sony than the PS3. Even though the PS3 has a higher "revenue", the profits from the PSP are greater. Does that really seem like "half a console" to you?

nice to see the ds doing great

But my list of Psx games beats any DS game you can throw at me (for me that is)

Well fo the PS1 I heard all numbers from 101 to 105 million sold. Anyways it should do it this quarter no matter what the real numbers are ;)

According to VGC,

PS1 = 102.49 million
DS = 102.12 million

Not yet, but by the end of next week, it will officially be the third best selling video game system of all time (GameBoy is at 118.69 million, PS2 is a moving target at 124.74 million)

Note: I am using shipment numbers for PS1 and GB, because VGC doesn't have sales data that far back.

It will catch both.

ps1? how do we know how much it has sold?

Could someone tell me if the PS2 sold more than the wii????
