Sure, everyone’s talking about Honeycomb (well, some people are), but if you just want a little hackable tablet on which to do whatever it is you do with a 7″ tablet, this Archos 7 is going for a bargain-bin price right now. It was $200 at launch last year, but as you can imagine, there is a bit of stock left over, and it’s available on eBay for $125 with free shipping. It’s from TigerDirect, but cheaper than they have on their own site.
Need something to use as a second screen, Twitter/RSS device, or home media controller? This thing might suit you.
