The HTC Flyer was the Taiwanese handset company's first foray into the tablet game - a 7" device with a 1.5GHz single-core processor, two cameras, an SD card slot, and 16GB of storage (digital stylus not included). At $500, it was pretty obviously overpriced. But for 300 bucks, the this tablet is at least nearing what we'd call the competitive range.
The Flyer runs Gingerbread, though a Honeycomb update is in the pipes, and its bootloader presents no obstacles to the flashing of custom ROMs. Having used the Flyer myself, I can say it's a decently quick device and is very solid feeling, and quite svelte in terms of dimensions. If the 7-inch form factor interests you, and the Kindle Fire's closed Amazon experience does not, the Flyer may be worth your hard-earned cash.
Personally, I'd still wait - with Black Friday sales coming after Thanksgiving, the Flyer (and a litany of other Android tablets) will likely get even deeper price cuts to get units off the shelves before the inevitable avalanche of Android hardware manufacturers will be releasing in time for Christmas.
The Flyer goes on sale at this price tomorrow, October 1.
