LeapPad assistance i do have questions
How does the memory hold up with all the downloads?
The memory needed varies between each item. Once you have things downloaded into the Leappad app on your computer, it is very easy to add and remove things from your Leappad (and it stays on your app center). You just connect your Leappad to the computer and move things around. For example you could load it up with videos for a roadtrip, but remove them if you need room to do something else. Once you pay for them, they stay in your app center so you can add them back at anytime.
The Leappad has 2 GB of built in memory. We have quite a bit loaded on ours and still have plenty of room. Here are some examples of the size of the apps:
Ultrabooks- range from 62MB-92MB
Games-range from 1-65MB
Videos- range from 50-133MB (Leapfrog ones are around 60 and nature type are higher)
Creativity-range from 25-75MB (the story ones are the larger ones)
Expansions-range from 5-15MB
eBooks- range from 5-35MB
Flashcards- range from 15-20MB
Whats the difference between a $10 game vs the $24 cartridge?
I'm not 100% on this one yet. A few of the games that we bought on a cartridge are now available as downloads for the $25 price. They aren't all available but maybe they are moving that direction. That would mean not having to use an actual cartridge. From what I can tell, the more inexpensive games are the more generic type- alphabet stew, jewel train, number bash. And the more expensive ones are branded or more extensive- Globe- Earth, Ni-Hao Kai-lan etc. The nice thing about the apps are as soon as you purchase them, they are available for download which could be very useful in some situations.
What does the expansion apps do?
The expansion apps are extra levels and activities for games you already have.
Is the stylus pen attached by a string?
Yes, there is a string to attach the stylus to the Leappad. You also get an extra stylus. The one in the Leappad when you open it doesn't have a string, but there will be another one in the box with the string- so just switch them out.
Did you buy rechargable batteries?
Yes, we are using rechargeable batteries. The kids played with it so much the first day we had to recharge! But we haven't had to recharge yet since then. Just jinxed myself- batteries need recharging.
How about the accessories? Case worth it? Gel Cover?
I ordered the case, but haven't received it yet. The kids like to take it in the car and I'm always paranoid it is going to be dropped. So I will be glad to have the case. It also holds 6 cartridges which is nice. The Gel Cover wasn't available yet, so I didn't order it. I like the idea of the gel cover for the extra grip. I am curious it would fit in the case with the gel cover on or not- I could see a use for both. Around the house the gel cover would be nice, but I also like the case to carry when we leave the house.
