699 is pretty good when taking into account the price of the most expensive Steam Deck.
The problem is, most people don't buy that sku.
Still a great price point when compared with other PC handhelds though.
One game wouldn't be enough to solve Xbox's problem's, it would be a start.
For me, they would need two years of putting out stellar products with maybe one or two misses thrown in just to show things are improving.
