Ah, geez, all the Archos haters come out of the woodwork, so I gotta speak up. No, I don't work for Archos, or anyone who sells their stuff.
About 2yrs ago I bought an Archos 28 for $99 my 7yo. He liked it, but the screen was too small for decent apps, so it was just treated like a really nice music & video player. It was worth the price, never broke, FW upgrades went without a hitch, and it did what it said on the box. No complaints aside from the twitchy resistive screen, and he just used a dull pencil as a stylus.
The Archos 28 stood up to the abuse w/o a problem, so I bought an Archos 43 last year as an upgrade. The kid just turned 9, and he still loves the 43. With Skype installed, it's pretty much a cheap and sturdy everything-but-a-cellphone, upgrades went fine, it's stable, doesn't crash, plays a billion games w/o problem, browses, gets email. Anyway, he'll graduate to an ICS phone in about a year (to coincide with moving from the schoolbus to the city bus), but this has been a fine mini-tablet.
In a pinch, I've borrowed his Archos 43 many times, and it's a very capable device. It does web, email, and tons of games no problem. He loads movies on it and borrows the hdmi mini-projector for sleepovers, and his iFruit friends are envious of the media support. Battery life is good, etc etc. It's the same generation as this Archos 101, which has a much nicer screen and bigger battery.
So I just don't get what all the Archos hate is about. This Archos series isn't a 5-star device, but it's not a 1/5 star either. The whole line is solidly middling, for dirt cheap. The 101 is still a solidly capable device with a *good* screen and tons of expandability for less than 1/4 the price of the bleeding-edge iFruit. It's an order of magnitude better than the random Chinese no-name ePad/iPlop/etc tablets that have no mfr support. Archos is a solid company that's been making mid-market equipment for years, and for moderately-able geeks, this is a hell of a deal. Don't believe me? Go browse around ftp://support.archos.com/ and have a look at the gobs of stuff they make available... and pay attention to the software and updates they keep making available for truly ancient systems.
If you know what you're buying, this is a solid deal: A 3-star device for a 1-star price. Just don't expect a 5-star device for the price of a cheeseburger.
