There's no doubt Amazon's tablet PC, the Kindle Fire, was one of the most-talked about stories this week. However, Apple's ongoing patent battle with Samsung and the dismal performance of Intel's appstore have also got our readers voicing their options. Here's the five most commented stories on PC Advisor over the past seven days.

Apple claims Samsung knew it was infringing its patents

This week in a court in Australia, Apple claimed Samsung must have known it was infringing Apple patents for the iPad with its own tablet PC, the Samsung Galaxy Tab 10.1.
Arb said Samsung shouldn't be worried. "Android is already bigger than iOS. So a handful of phones & pads might have to be withdrawn from sale, but there will be dozens in their place (as opposed to one iPhone/iPad per year)."
Meanwhile, Maccyroo described Apple as being 'potty'.
"ALL Tablets resemble each other in that they are all rectangular touch screens with a mostly pain and uniform frame [with slight variances in width] around them. It's like Sony and Panasonic suing each other over TV designs. TV's are also all rectangular with a large screen. Why can't Apple be happy that they "invented" the first popular multi use tablet?," he said.

Amazon Kindle Touch not available in the UK

Amazon's newest eReader, the Kindle Touch, hasn't been made available in the UK. While the cheaper $79 version (£89 here) has hit British shores, there's no sign yet of the more expensive touchscreen version released this week.
Art Mayo said it was "poor going" on Amazon's part. "They've had ages to prepare this new version for release. I guess that means no Kindle Touch for Christmas in the UK - the nation which publishes more books than any other on earth. HUGE missed opportunity." Meanwhile, Martyman was unimpressed with the touchscreen element of the eReader.
"Looking at some of the demos, It looks like it will take MORE effort to turn a page. I don't know how others use their existing kindles, but I tend to hold my device with my hands on the side and just casually press my thumb on the page button. In fact my thumb usually rests on that button anyway. It now seems turning pages may now induce a severe case of RSI," he said.

Intel hopes to boost flagging AppUp store

Intel revealed it is making some changes to its AppUp store in hopes of improving what it admits has been dismal usage. During its AppUp Elements conference for developers in Seattle, Intel said that 807,000 applications have been downloaded and 350,000 consumers have registered to use the store. The store, which launched in 2010, was designed to spur application development for netbooks. It also includes apps for PCs.
Mark_Simpson said his one experience of the store was "so appalling" he never bothered to use it again. "Tried to install an app, and got Error Code messages. No text, just a number. I then spent an hour Googling, the trawling AppUp's support forum, only to find that the error code related to the fact the app would not work with 64-bit Windows 7. This from one of the main companies pushing 64-bit computing," he said.
"They might want to concentrate on making the damn thing user-friendly first, before rolling out extra features."

New guidelines on the use of 'unlimited' in broadband speeds published

The Committees of Advertising Practice (CAP) issued new guidelines this week designed to clamp down on the use of 'unlimited' and 'up to' in broadband advertising.
The-chief revealed he pay for, 'up to 20Mbps' but has never achieved more than 4.2Mbps.
"Why can't ISP's be made to charge by Mbps achieved? After all, when you sign up, most of them test your connection and tell you the maximum your line can give, in my case maximum 5Mps," he said.
"If you ordered an Audi A6 2.0 TDI and paid for it, then the garage gave you an A3 saying it's all your local roads can take, someone would end up in court."

Visa Europe unveils new mobile payment system to rival PayPal

Visa Europe this week launched two new services to help consumers manage their money and make payments using their mobile phones, one of them to rival PayPal. The Visa Mobile Person-to-Person payments service allows registered users to transfer funds to any Visa cardholder in Europe from their mobile phone.
Steve said: "What I like most is the fact it has been developed for Android before the iPhone. It's about time someone realised there are more Android phones in the wild, therefore a larger market available."
