Also this question affects uses and price very much. At Apple, for example, you pay for each doubling of the main charge 100 euros. A 32-GB iPad costs 100 euros more so than one with 16 GB as and the Google Nexus 10 is the same principle. Samsung gives himself as modest demands such as for the 32-GB model of the Galaxy Tab 2 7.0 only 40 euro premium over the 16-GB version.
How much to be disk space you need, it depends largely on how one wants to use the device. Only those who wish to take a lot of music and movies on your tablet needs a 64 GB version. Users who mainly want to use their tablet at home probably, mostly needs rich 16 GB of memory. That is enough for several dozen apps, a little music, photos and maybe a few videos or a movie. If you are not sure, go for 32GB of storage.
Can you expand the memory?
If the installed memory but one day become scarce, you are better off when the tablet has an expansion slot. Via microSD card can be retrofitted then, for example, 32 GB of memory for 20 to 25 euros. Apple offers this possibility in principle as and a few other manufacturers have followed suit.Some manufacturers combine their tablet with a certain quota free online storage. At Apple, you get 5 GB of iCloud storage at Samsung have 50 GB with Dropbox, but these are limited to one-year service life. Alternatively, there are plenty of other free cloud storage offerings. The Strato AG in Berlin, for example, offers 5 GB of free storage to anyone in the offer Hidrive, which makes it very practical as and free apps for iOS, Android and Windows Phone 7 that are available.
What use to me UMTS, HSPA, LTE and 3G?
As well as additional storage is expensive, you have access to a wireless connection also some deep pockets; however, wireless is built into all tablet computers. However, the good is of course just a little, as long as one stays at home in the private WLAN, at the office in the corporate WLAN or traveling in public Wi-Fi hot spots.
