Looks like we’re all indebted to HP in one way or another. Since the TouchPad fire sale began, we’ve seen a noticeable southward shift in tablet pricing — it’s as if iPad rivals finally figured out that battling on price was just about the only way to make a dent in Apple’s enviable market share. Now, we’re seeing Fusion Garage wipe a full $ 200 from its Grid 10 tablet… before the thing even ships. If you’ll recall, the outfit was aiming for a September 15th release date here in the States, with initial pricing for its 16GB model set for $ 499 (WiFi-only) / $ 599 (WiFi + 3G). Out of the blue, those pre-order rates have plummeted to $ 299 / $ 399 this morning, giving prospective Grid OS adopters entirely more motivation to buy in. It seems that Amazon hasn’t received the memo quite yet, so those hoping to get in the low-cost line should scurry down to the source link. Naturally, we’ll be bringing you a full-on review as soon as we procure one, and we’re guessing that just became a lot more relevant to your interests.
