If they didn't have a $99 model, one would think the $150 is expensive. There is have a crippled, just slightly lower-priced model so that people who want to "optimize" the price think that they're so clever by getting the level-up. Just like one thinks "Cool, I'm getting twice the amount of pop for 25 cents more!" but you would have been happy with a single can of Coke for a dollar, now you have a 32oz cup of fountain Coke for $1.75. Regarding the battery (Flex owner here), I find that the slightly-more-than-once-weekly charging schedule annoying. If it could last 8 or 9 days, I would just charge it at the same time every week. Now I have to keep monitoring this thing and figure out when's a good time to charge it so I don't miss steps.
