NEW YORK (

TheStreet

) --

TheStreet

, led by myself and James Rogers, held its inaugural tech chat last night on

Twitter

, with readers and followers asking a variety of questions.

Using the hashtag #TSTTech, users asked about a variety of topics, including

Apple

(AAPL) - Get Report

,

Google

(GOOG) - Get Report

,

Salesforce.com

(CRM) - Get Report

,

Amazon

(AMZN) - Get Report

and others.

Tim Cook's performance since taking over from Steve Jobs, the iPhone 5, and earnings results from a slew of tech companies were among the more notable issues discussed.

Twitter user

neumann04

wanted to know about

NVidia

(NVDA) - Get Report

.

Twitter user

KavehKM

wanted to know about

HP

(HPQ) - Get Report

and its

second-quarter results

.

Follower

LKulikowski

wanted to know about the

iPhone 5

, and what consumers should expect.

Davidspeltier

asked whether there was any value in HP, which is trading at 4 times earnings, and

Dell

(DELL) - Get Report

, which is trading at 6 times earnings.

Bbolan1

pondered whether there were really budget constraints in IT departments, or if managers were just saying that to Dell and HP salespeople.

KavehKM

was back with another question, asking whether we're in a tech bubble.

Many have asked the same question, given the prominence of companies like Twitter, the rise in Apple's market cap, and

Facebook's

(FB) - Get Report

IPO debacle.

KavehKM had another question, this time about Google's own tablet, the Nexus 7. Priced at $199, this tablet is seen as a formidable entry in the low-end market for tablets, as companies try to eat away the iPad's market share.

RobTheStreet

wanted to know what new, unmentioned, product Apple could build to create a new revenue stream. He asked whether we could see an

iCar

.

Everyone believes Apple will get into the

television market

one way or another, particularly since Steve Jobs told biographer Walter Isaacson that he had "finally cracked" the technology.

DylanPetrin

wondered how many iPhone and iPad sales were priced into year-end, given strong earnings from Apple suppliers.

KavehKM asked about

Apple's CEO Tim Cook,

who took over from Steve Jobs one year ago today, and the job he's doing replacing the tech icon.

After Salesforce reported

second-quarter earnings

,

@davidspeltier

wanted a quick take on the stock, given it fell sharply in after-hours trading last night.

KavehKM wanted to know why Amazon trades at such high earnings multiples.

The final question from KavehKM was on Facebook. She wanted to know whether it could overcome the mistakes from its IPO.

xtranger51

wondered if Apple was expensive. Apple recently became the most valuable company in the world, and set an

all-time high.

The last question of the night was on Amazon, and whether it was a "smart buy" given the company's announcement of a press conference for what many expect is the next version of the Kindle Fire.
