iPad, Android, Kindle, or Windows tablets.
Mike wants to use his Kindle to read comic books. Leo says there's a far better option, and it's owned by Amazon as well. It's called ComiXology. It's designed exactly for reading comics, while the Kindle is really made for the written world.
ComiXology will enable him to zoom in and out, and it also works with all comics. He can use it on his laptop too. The Marvel Unlimited app has an all you can eat monthly subscription, so if he's a Marvel fan, it's the way to go.
Nick has a Samsung TV and he wants to cast videos from his computer or tablet. Leo says that most TVs support DNLA, which would enable him to stream to the TV. Samsung calls it "Samsung Link" or "All Share." He should Google the TV model and "DLNA" or "Miracast" and he will find out how he can do it. It may also be called "screen mirroring."
Most Windows devices and tablets will support DLNA. The Samsung Galaxy Note would be a good tablet choice, as are the Galaxy Tabs. Leo likes the Galaxy Tab S2. Any Bluetooth keyboard will work also, and the TV will support it.
Shirley is retired and is looking for a computer. Leo says that a Chromebook is probably the best option for Shirley, and she'll need an internet connection. Shirley could also get a Chromebook with LTE.
Another option is a tablet like an iPad or Samsung Galaxy Tab. She shouldn't get a cheap one, though. Leo advises getting one with LTE so that she doesn't have to rely on Wi-Fi. T-Mobile is a good option. Leo also advises a deal of $25 with unlimited data from them when she buys the tablet up front. That's a good deal.
Walter has three iPads and using Speedtest, two are always slower than the third. Leo recommends using DSLReports.com. It runs through the browser and it will give him a better result. Why the iPads are different with speed tests is anyone's guess. It could be age of the iPad, consistency of the test, etc.
Brett has an older Dell Venue tablet and wants to update it, but they don't support it anymore. Leo says that his only choice is to root it and put a custom ROM on it. Leo says the first place he'll want to go to put a custom ROM on Android is the XDA Developers Forum. He can get step-by-step instructions for his exact model. There is a Dell Venue section, but he should be sure he uses the exact model or he could brick it.
Dave wants an app that would allow him to use his iPad Pro for work by handwriting notes and saving them to Word documents. Leo says that there are dozens of apps out there, but it depends on how good his handwriting is. The iPad doesn't have built in handwriting recognition. Here are some good options to consider:
Matthew wants to take paper notes with handwriting recognition and he wants to know if the Surface Pro will suffice. Leo says that the Surface Pro is fantastic. It's a tablet with an attachable keyboard (he should get the type version). It comes with a stylus. He can use OneNote to do it as it's tightly integrated.
Jose is having trouble with his Samsung Galaxy tablet. Leo says to go into recovery mode to get it back to the factory default settings. XDA Developers may also have a firmware image that he can then replace it with.
Stephanie would like to build an app. How can she find someone who can help her? Leo says that app ideas are a dime a dozen, and the trick is how to get the right person to make it and market it. There are great places to find a programmer. eLance is one such place. She should ask for references.
