Not that big a deal I suppose with both the Android Market and AppBrain doing push installs from their web sites. Both being tied to your gmail account that the phone uses.
My one concern about tablets is, why would I pay more for a tablet, with less memory and storage than a netbook with a hard drive in it?
Most tablets have up to what 64GB of memory with being able to use an SD card with up to 32 gb for $250 to $800 bucks verses a netbook, with a bigger screen in most cases, and a much larger HD 100GB to 300GB or more if they are user upgradable. For the same price range as many of the tablets.
